Buyer's Guide: Your first neodymium magnet
Вставка
- Опубліковано 3 жов 2024
- Neodymium magnets are so powerful that you should watch this before buying one. I give guidelines for size, shape, grade and coating. In this way you hopefully will have a good start with a nice beginner magnet.

I have no personal experiences with magnet webshops outside Europe. For US/Canada it seems that www.magnet4less... has the best selection at very fair prices. I haven't found any sample sets in their webshop though.
Another cheap source for neo magnets are scrapped hard disk drives. It can be tricky to open the drives though and the magnets are specialized. Here's my video about them: • Magnet in HDD | Taming...

I love this guy's voice! Most people are extremely boring to listen to when given scientific subjects, but this guy has the sort of voice that one can listen to hours for. Great video Brian!
MrNoodless Thanks! I believe I'm getting better at the voiceovers...
***** Yes :)
Say that again. Very good voice and intonation indeed. I also follow an Australia based guy who has tons to tell about electronics. Very very interesting but after half an hour you end up all wind up.
+Kurt Schatteman I think I know the Aussie you're talking about but I forgot his name. All I can remember is he dissembles things like meters and did a tour of a TV transmitter. If that's the same person could you please let me know his channel name. Thank you.
+RMoribayashi it's Dave from EEVblog - just google him...
Whilst the channel is small, the content is huge! I love your videos, they're incredibly informative and terribly interesting! Thanks for taking the time to make these! I really appreciate it!
Luke Paul Thank you very much! Always nice to hear that I am not just wasting my time making these videos :)
Brainiac75 pleas help i am buying 10 pieces of neodymium magnets and and i am being asked about the dimensions so what is the best i am a 1st time user?
+ Omar Taman Hi, you're asking for something I give you guidelines for in this video you have commented on? To sum it up: go for a cylinder magnet that isn't very thin and don't go over 20 mm in diameter for your first magnet.
Brainiac75 12mm diameter and 3mm thickness nickel coating is good because i trying to get 10 pieces and the asked me about its dimensions so?
+Omar Taman 3 mm is thin for a 12 mm diameter magnet. Expect to break a lot of them if you aren't used to handle neodymium magnets :)
As a diesel mechanic who has worked on gigantic generators that started my career selling and installing upgrades for cars and trucks I can really appreciate the magnet/Ferrari analogy. I was watching this video with my 7 year old who wants to get some magnets because of this channel and you immediately won me over lol.
Where's the best place to get a big square one?
Very wise advice even after all these years I still get bit from time to time. Many blood blisters in my past.
So when a friend casually passed a disc magnet the size of my palm and 2 inches thick to me he was amused by the seriousness and respect with which I handled it.
OMG! That is big
I vote for the vid of the macho thing :D
Stefano
Me too!
Stefano i vote for it too!
Stefano +1
I love the way you warn people. The Ferrari for a first driving test was hilarious.

Thank you for watching :)
+Brainiac75 are you German?
BlackSheepTV Nope, I'm Danish.
horrible analogy
@Marvin Connor bot
Hi Brian, we truly love your videos! They are informative and very entertaining.
supermagnete Thanks for watching and commenting :)
I bought some neodymium magnets that are about 1cm wide and .5cm thick and even when these come together it's hard enough to hurt quite a bit when it pinches my skin. It's also nearly impossible to separate them by brute force, without sliding them past one another. Not to mention how many uncoated magnets I've shattered into dozens of tiny, razor sharp pieces by accidentally letting them snap together. It takes a LOT of vigilance to handle even small magnets like that properly. I couldn't imagine a "monster" magnet.
My first try is a 1cm disc I bought from a hardware store and I love it.
It's so versatile because of the small size, I can use on everything and carrying it to everywhere easily.
Once again a really nice video.
Allthough I' ve got over 2000 neodymium magnets in different shapes and sizes( mostly 5mm balls), it's also a guide for me.
Sorry for my bad English and spelling mistakes, I am German.
Magik Max Thank you! The 5 mm spheres are very popular and with thousands of them you can make nice shapes and sculptures :) And your English is good - no problem.
Do the macho set. I would like that :D
your soothing voice is helping my crippling depression during the pandmic. thank you!!!
I bought a variety of neodymium magnets, the largest having a 405 pull. Following your advice, I began experimenting with the very smallest, a 39 pound pull, 1 inch cup magnet. I have experience with very large ceramic magnets, so I had great confidence.
I now have a small blood blister on one finger, and a greater respect for magnets. Had I ignored your good advice, I could well have had a crushed finger with the largest magnet. Thanks for your fine advice.
Thanks for sharing. Neodymium magnets can be fun, but when measured in whole inches they are not toys :)
OMG! 405 pound pull
I've only just come across your videos and of course was immediately off to buy the largest Neodymium magnet I could find.... Then I saw this video.. .Perfect! I then realised I would be making a mistake and set my sights on the Z-13 set as you've shown here. Alas, the 2 companies I've seen you show in your videos deliver outside europe so I'm now off to see if anyone local (Australia) has them. They probably will, at double to triple the price alas. Great videos, informative and interesting, keep em up.
+Terry Wood
Thanks! And yes, shipping neodymium magnets intercontinentally is not easy/cheap. They are only allowed on airplanes in well-shielded boxes. I know nothing about the Australian market - good luck with it :)
Hey thank you very much, Brian!!! :D I was able to finally buy my first Neodymium Magnet! Im just a beginner, and thats why im very thankful that youve made this video! By the way i was youre 300,000th subscriber! :)
I started off with a 1" cube N52 neodymium magnet. Max 140lbs of force. Seriously a dangerous toy.
i started off with baby 10*6 mm
and now i have 50*50*25mm
(death magnet by its nickname)
tho i bought the N35 version not N40 so it only 50kg not 100
I started with a 30x5mm N45 neodymium magnet that has 23kg pull force.
Well I saw a neodymium magnet with 116kg pull force certainly the most dangerous one
My magnet was the largest disc magnet the website that I used had. (I didn’t use supermagnete)
Awesome! Relevant today as it was when published six years back.
That was a very well made video. You taught me a lot. Thanks for making it.
Please do a video on the macho set pleeeeease
Arvid qqu
Need... macho... set... video! :D
Excellent guide.
yeah true
I took my driving test in a Cadillac. You might not think of those as being tough for beginners to drive, but they are. Not because they're fast or squirrely, but because they're HUGE. They're expensive too, especially the older ones.
Thank you for taking the time to make this educational video, especially the warnings. I myself really learned a lot by watching, i never really thought about how dangerous magnet's can be until i watched this video.
Please be responsible everyone, and keep powerful magnet's out of reach of your children, if you have magnets that are strong enough to crush a grown mans hand, little fingers and toes don't stand a snow ball's chance in h3ll.
My pleasure. Small kids and large neodymium magnets is definitely a bad match. I also hope that people are responsible, so everyone is safe and large neodymium magnets are'nt banned.
No ceramic plates were actually harmed in the filing of this video. 😂
I'm allergic to nickel. So I'm glad you went into the detail of what they are coated with, thank you.
Gristle Von Raben You can also find some that are zinc-plated. They're very resistant to corrosion too, without being as expensive as gold-plated ones.
Gristle Von Raben You're welcome :)FlipUltraHD's advice about the zinc-plated magnets is a good advice. The 4-layer coatings like Ni-Cu-Ni-Epoxy or Ni-Cu-Ni-Au have so thin layers that even tiny scratches will expose the nickel underneath.
Me who bought six N52 1-inch cubes to send a pinball into orbit: * walks away whistling*
Since ca. a half a year I have a magnet in my finger.
It's not very useful except for picking or holding up small screws.
However you can feel electro magnetic fields with it which I find really interesting because sometimes you feel it in places you don't expect and in addition it's something a normal human doesn't feel.
Excellent guide to these new type of magnets
I've bought a set of 50 N52 disk magnets in the size of 10x3mm, and even they impress me very much!
+Seegal Galguntijak
Yes, N52's are impressive no matter the size.
I use Neodymium magnets in my hover board.

The way of expressing and your language is understandable thank you for your service to people's
I came here after immediately pinching my fingers between two small disk magnets that I just purchased. I should have known better, having been already been a subscriber to this channel for a while
i bought my first neodynium yesterday and it's a 6 inch magnet, very very expensive but so powerful. I use him to tidy my room's metal items
How expensive
Nuts .
those magnets are no joke, they are so powerful I still have the 12 inch magnets are still stuck together, and I can't get them apart
If you don't mind a 3 or 4 week shipping time then EBay has a boatload of sellers with excellent prices. Most of them are from China and the finish of the magnets are usually not superb but you can get an N52 40x40x20mm square type or a 40x20mm round type for about $15 and shipping is free. The photos are not faked so at least you can see the finish quality and decide for yourself. I've purchased them from Chinese sellers on EBay and am quite satisfied!
Sometimes the dimensions are a bit off. Like maybe you will order a 40x40x20mm magnet and when you get it it's actually 41x37x19 - but hey, that pretty close. And also so far my gauss meter says they are within one rating of what was specified. So if it says N50 on the seller's description then it could be N48 or it could be N52. But in all honesty there is almost no difference between N44 and N52 for example. You can't tell and even the gauss meter has trouble, lifting power is the difference between something like 190kg and 200kg.
Loved this. Hilarious and practical advice. The Ferrari analogy was pure gold. Keep it up!
You really need to make a video about the Macho set. Very interesting.
In my opinion, a long cylinder would be best for a beginner. They are easy to handle because they have a lot of room to hold on to, and can be most easily controlled when letting it contact another magnet or metal surface. I like cubes and blocks for how they look but a long cylinder is most easy to casually play with. I carry a .5x2 inch cylinder magnet with me and it handles pretty nicely. Though do be careful what you set on your lap when carrying a magnet around, I almost ruined my laptop fan once.
+KingofHearts67
Cylinder magnets are the easiest to handle, no doubt about it. I just have trouble with recommending them since you pay for a lot of length of magnet that is not really adding much power. A 10x40 mm cylinder magnet is 4 times more expensive than a 10x10 mm disc magnet. But it is far from 4 times as powerful, only around 20% more pull force... So measured in power a cylinder magnet is not good value for money. It's still a nice magnet though :)
Excellent video... And I'm NOT a beginner! Just a great, well presented introduction. Kudos!
+JohnnyJim J
Thank you very much! Experts are also welcome :)
Thank you for making this safety and information video.
OK Sure
*goes and buys an 100 mm N52 Cube and opens next to radiator*
I hot an eyebolt magnet that can lift around 120kg
my first neo magnet was 10*6mm rod shape
I bought a few "small" ones a while back. And they were surprisingly powerful....and painful!
Hello
I am so used to getting pinched by big ones that i kinda feel nice
@@TheRadioactiveBanana32 even Alnico is giving me pinch i bought disc magnets of 90 mm * 36 mm * 15 mm disc Alnico magnets and it's giving me pinch whenever i try to stick them together.😭
We need the macho set video! Now! I can't stand the cliffhanger D:
Awesome list, Awesome recommendations, Awesome warnings. Nice job and well done!
Actually there's is a cool magnet shop in my country, I usually buy little magnets from them. I just walk in, say what I want the magnet for and they can show me how they look, I can change my mind and pay. I don't buy much magnets but when I need some I know where to look :)
Nice, we don't have such a store in Denmark. For me it would be funny to visit one :D
your videos are always so informative. Thanks for sharing.
It just so happens that there are a few warehouses of neodymium magnet stores here in Texas where I am, in fact in the same town that I am in. I can literally go over to the place and buy magnets straight from the store. It is the Applied Magnets store. You may have heard of it. There is another one that I do not immediately remember. Applied magnets at one point sold 1/2 inch grade N54 magnets.
+QuestionXV Lucky you :) And yes, I did see the N54 magnets they advertised with. But they quickly stopped selling them - were they underspec or just a one-time offer? I don't know.
Here I am over a year later, I'm still amazed that I have one of the biggest neodymium warehouses in the world less than 15 miles from my house, I live in Plano and the warehouse is at 1111 Summit Ave #11, Plano, TX 75074, and there is another warehouse, the one for CMS Magnetics, 1839 Wall St, Garland, TX 75041. That should give some people here excuse to move to Texas, by the way, congratulations on almost 200,000 subscribers.
Thank you :) Yes, and I still have to import the magnets from another country if I want a decent size...
You probably saved my fingers. Thank you for your video.
He was so true. I bought two 20x20x10 square neodymium magnet. and I tried to seperate. Neodymium magnet was so strong. neodymium magnets pinched my skins with sharp corners. that was so hurt :(
So buy MUCH SMALLER than YOU THINK.
and I need to learn grammar
i bought some 20×15 cylinder magnet. i really underestimate their power until one if em start flying so fast and broke it.
They are really strong people.
like *really* strong
Great videos. Really well done on all I have watched so far.
Because of you im gonna buy a quality magnet. ty very much.
I have several hundred small disk neodymium magnets that I used with model kits to hold parts that I wanted to be removable or changeable with other parts, and I will say even the tiny ones will bite you with some force if you let them.
Yep, once in a while even small magnets will remind you of how powerful they are ;) But not a permanent reminder like with the big ones :\ Thanks for watching!
I have a 10x25 mm Disc magnet. I had been working with my agnets over 10 months
Thank you! :) your videos are super informative and helpful.
MACHO SET!
My first neodymium magnets ware some cubes that i think can lift 1 kilo and i also got a block that can lift 25 kilos
Wow. NICE!
Hey, really really really useful video for mortals like me!!! Thanks a lot for the info!!!! You rock!!!
Macho set! Do a Macho set video! MAKE MORE VIDEOS I LOVE YOUR VOICEOVERS AND SCIENTIFIC INPUT!
Most helpful - thank you!
I like these magnets I want to get some more I have small ones. They can be really useful!
how much do you think a N35
50mm×10mm disc magnet will lift??
17kilos on rated box but maybe wrong
Absolutely beautiful, Love your videos.
Gotten my set coming in the mail, followed majority of the guidelines you stated, probably somewhat of a slightly larger magnet (.56 in^3) but pretty close.
As long as you're prepared and don't start with slamming the magnets on a large piece of iron with your fingers between, you'll be fine :) Thanks for watching and good luck with the magnet.
Brainiac75 Well they arrived today, probably my happiness took away part of my preparation as putting them on a table and the magnets swiping around the area ends up two chips from two of them coming off. I decided to put the two that shattered away to keep them away from moisture so they don't corrode as quickly. Well thanks for the good luck, although maybe a shatter there's always plenty of time to get better handling the magnets. :)
Very very good. Cant give you enough thumbs for this one. Good advice, not lame choices.
gamingSlasher Thank you very much. Glad that you think I made a fair compromise between safety and power :)
This is a very helpful video I appreciate it!! Very in detail!
Machinists magnetic base, very strong but you can keep them tuened off until they are in position.
With Great power comes great responsibility
Wow, Amazing video, I have a new found respect for magnets as I tinkered with a few smaller one's and still got BIT, I now know to be far more careful. I pulled apart several hard drives for their magnets and I am amazed as to how powerful they are I can not imagine the really large ones. But I digress...
Great video, yes please do a video on the Super Magnets, as I know in my heart of hearts I fear them now and if you don't do such a video I will never know...
I bought a water cooling kit, used, and it had these very thin, like almost paper thin, 1/16th of an inch or thinner then a typical coin, but they are very powerful as I use them to hold various tools like snipes and pliers. They must me Neo's because they are very strong, I might venture to say probably 48's, if they are 52's I am very impressed. Either way they are round and BIT.
The Magnets pulled from hard drives are very powerful, surprisingly powerful to say the least and I left the metal attached to them as it seems to control their power a lot and makes them far easier to handle. Even with the attached metal shield they are still fun to play with, at least I know I will not crush my fingers with them where as if they are removed from their shields they will be very dangerous to handle.
Thank for sharing this awesome video....
Paul Bialozor Hehe, yes they are surprisingly powerful. They seem so innocent until a large piece of metal comes close to them...Neo magnets from scrapped hard disk drives are a cheap solution. But opening the hard drives and removing the magnets from their brackets is not always easy. And the magnets are quite specialized (my video about them: ua-cam.com/video/ep_VCotA1ZY/v-deo.html). But especially the really old hard drives can have some large impressive magnets.
Thanks for watching and commenting!
brainiac75 Great to know, I have some very old Hard Drives, like 200 MEGs not GIGS, Megabytes... I look forward to dismantling them...
Thanks so much for your reply. I envision the storage of magnets, much like the storage of isotopes, where they store them in "bird cages" (If you Google, you will see what I mean) where the magnets are stored in a binary fashion, but not in close proximity. Perhaps there is more structural safety in such a binary approach? I wonder at what point do the materials break, and what if we just had just essentially a powder instead? Certainly, a mechanical system could be devised to variably bring many individual magnets closer together, and then seperate them. A simple PVC frame could be used to do that, provided that only smaller magnets were used.
How far can you cause deflection of a compass with your large is something I wonder?
I found that recycled speakers do a great job. They are easy to get and are very powerfull.
Lol det var først 2-3 dage efter jeg subscribede til dig at jeg opdaget at du var fra Danmark...
There's also first4magnets.com in the UK, they've got many kinds of magnets including the high-grade N52 ones. They don't have huge magnets, but their largest can lift 150kg, enough to mush your hands.
I got my first one from there, it was a small disc magnet that could hold around 27 kg. Good little starter magnet.
Can you make a video about the reasons for all the different types of magnet coatings and their uses? Zn, Ni, Au, Epoxy...
Thanks! Great videos by the way!
Thanks! The different coatings have different properties, but for the average user they are only a matter of asthetics. For eaxmple, gold just looks good and has no practical purpose.
Zink is a cheaper solution and good for people with nickel allergy, that shouldn't handle magnets with the standard nickel coating.
Epoxy is better for protecting the magnet against moisture in the air, but still can't be submerged in water. For that you need teflon- or rubber-coated magnets, that are even suitable for saltwater.
I bet the ring magnets would work great to ties a rope to, to use in deep water. My gramps used to have something like for ice fishing.
+Brainiac75
you said that the gold coating was not an enhancer of magnet strength but it is an excellent conductor.
two questions. (and please don't electrocute yourself experimenting)
1. can you turn a regular magnet into an electromagnet through some simple process?
2. if you apply electricity to a magnet coated in gold, how much electricity would it take before the coating melted off?
3. is there a coating that can be placed on a magnet, that's as conductive as gold, but has a higher melting point?
i was sorta of beginner but i still bought 150x50 N45 disc-shaped neodymium magnet... and i can say it was a mistake... despite i clearly understood it's power i cant really handle it at home cause it attracts metal objects in 1 meter radius... however its fun cuz that thing can lift up to 100kg while being separated by 20 mm wooden table. Also throwing a metal grid on this beast with a apple on it slices it in little cubes in no time :)
U dumbass
1. Do you know where the magnets in the kits you show are manufactured?
2. Are magnets typically marked with the North and South poles on them? If no, why not?
I would recomend buckycubes as your powerful magnet
There are some weird shape very strong magnets in a hard drive, if you open the case. They are much stronger than fridge magnets, but I doubt they are close to Neodymium or other rare earth metals, but I don't know what are they made of.
Brilliant video. I am enlightened.! Thank you
Thanks man good stuff.
This video is very useful
I recently upgraded to a 2" x 2" x 1" magnet after having two 3/4" diameter x 1" magnets for a long time, inspired by your videos :) Do you have any suggestions for what I might get next if I eventually get another one? (Or something particularly interesting to do with that size?) Really appreciate your videos!
Benrob55 Thanks :) Personally I would go for a 2" cube. The extra thickness makes it a very powerful magnet. But only buy such a monster if you have handled the 2x2x1 without any incidents ;)
What kind do you now have?
@@karenmmcthree I have a 2x2x1” block and a 2” diameter x 1” disc. I didn’t end up getting a 2” cube (yet...). And I keep the block and the disc on opposite sides of the room haha.
@@Benrob55 where did you get it? Thank you
@@karenmmcthree I got them on Amazon.
Thank you for the video 🙌🏼💯
Is it bad I flinch when he broke that plate
Do a review on the big magnets please
Great glad I watched this first thanks!
I for some reason havnt used tools to separate 25*25 mm disc magnets but i have been fine with them i can easily seperat a 25*25 and 50*10 mm magnet by hand
Am i super strong?
nice video and info bro keep it up
thanks. i have been buying too thin and straight lined. All end up shattering. plus i need to mark the poles. Small thick disc for my next purchase. Tyvm
You can get big ferrite magnet in speakers
Really interesting, beyond being very powerful I knew nothing about neo magnets before this! Tell me, do neo magnets degrade over time, if so how quickly?
Thanks for watching. Neo magnets do degrade a little over time even if treated right (no excessive heat, vibrations, hard hits, radioactivity above background radiation etc.), but neo magnets are the hardest of all permanent magnets to demagnetize. A well treated neo magnet will not lose enough of its magnetization for you to notice it in your lifetime. I've heard figures like they will last for hundreds of years. But since they weren't invented until the 1980s we really don't know for sure yet :)
I bought an 30 x 10 disc magnet and 10x10x10 square magnet as my first neodymium magnets
Awesome channel!
+James Cooney
Thanks!
Very informative video. Thanks.
Me watching this after having bought 2 40mm x 40mm x 20mm half cube neodymium magnets (I am unable to pull them apart, and am afraid to fully do so in knowing I will have to put them back together. I have also pinched my fingers many times. I will not stop nor learn)
Please make a video on the macho set
my first neodymium magnets are 20mm long and 4mm high n45 grade. those little magnets can pack a punch! but now i want a 10mm x 10mm neodymium magnet.
smallenginedude71 I can understand why. A 20 mm wide magnet only 4 mm thick will break easily :)
brainiac75 thanks for the reply!
i have indeed broke 7 out of the 20 magnets.
I would like to see that video about the 'macho set' :P
