Finally i do understand how an electric motor works. It was not until a fan in a laptop broke, that i learned how a motor works, same as a engine, it needs a timing when there is 0 energy. All motors need a commutator whether its mechanical or electronic, it's the same principle like the valves of a 4 stroke engine. In this example the commutator is the moment the force of repelling makes the rotor to do half a turn, because there is an input energy higher than the needed to push the coil, it goes to the state of 0 and beyond and gravity does the rest, i wonder if you can make this with a flywheel but i assume it would be very inefficient than just using a commutator that switches the polarity of the coils. So, all motors are alternating current devices.
How long does the battery operate? My child is doing a science project for school using this DIY motor to see which battery brand would last the longest. All different battery brands we used only lasted less than a minute.
Reacted the project with crafting cooper wire. I utilized no paper clips only copper wire. I only sanded the ends of the piece I placed inside as suggested, worked well. I did used the a several regular magnets.
In general, yes, moving a wire coil in a magnetic field will function as a generator. At this size it won't generate much useful power but it will work as a proof of concept. If you search our website we have several projects where you can build small generators that will light up an LED.
What is the need of the battery? A changing magnetic field over a closed conducting coil caused by the initiated push should induce current and Lorenz forces in opposing directions in the coil, which then contributes to the spin. But, why do is that current is being supplied over the loop as well?
please show me how to fix it, I followed the instructions like your video but I used a bigger battery (maxe II) but the copper wire still can't rotate, I used a tape needle to make a pillar at the 2 poles of the battery. the battery and the magnet I use are black magnets
Make sure that your clips are laying on the battery, also try to rotate the magnet. You need to have the half - sanded side on the + side of the battery. I´m still not sure why, but otherwise it didn't work for me.
I wonder if the wire I used is wrong, or the magnet, does the wire need to stick to the magnet even if it is not attached to the battery? mine doesn't stick.
Hi - if you are a K-12 student working on a school science project, you can ask for help in the Ask an Expert forums on our website: www.sciencebuddies.org/science-fair-projects/ask-an-expert-intro. We will be able to help you more there.
Don’t do this you can actually cause the battery to combine the positive and negative electrical current, which will make the battery get really hot and explode
We have not tested it but this project should work with a range of wire thicknesses around 28-30AWG. If the wire gets too thick then it gets harder to bend, if it gets too thin then it won't be stiff enough to support its own weight.
Alright, I got a thicker wire though. By the way, what happens if I accidentally sand both ends fully? Is there any way to solve that? Or that doesn't matter?
@@Science.Buddies Ok, I got it. One last thing, does the item you use to make the coil matters? Im using a pencil/pen instead of a marker so the coil will be kinda smaller

If the thin copperwire breaks while building my motor, can I re-usethe copper wire together?Please sir answer my question quickly because it is my school project there
Please see the FAQ on our website for troubleshooting tips: www.sciencebuddies.org/science-fair-projects/project-ideas/Elec_p051/electricity-electronics/build-a-simple-electric-motor#faq
Does it have to be a copper winding or could I use a copper crush washer and solder a coper rod accost it? I guess what I'm wondering is if it's the mass that matters to act as a load or if the individual wires play a part?
The coil of wire acts as an electromagnet, generating a magnetic field that interacts with the field from the permanent magnet. Since the wire is insulated and coiled into a loop with multiple turns, it generates a much stronger magnetic field - you wouldn't get the same effect if you just soldered a washer to a single straight wire.
@@Science.Buddies Thanks for the reply. I got to thinking about it later that day and decided there must be a reason for windings or our motors would have copper straps in them. Engineers tend to know what they're doing. lol
"could I use a copper crush washer and solder a coper rod accost it?" If you did that, you wouldn't be doing much more than shorting the battery. It would get too hot to touch, and it might explode.
No, the magnet is not supposed to stick to the wire, but that may happen if the magnet is too close to the wire while current is flowing. If that happens, you need to re-bend the paper clips to move the wire farther up.
@@Science.Buddies Yes thank you, I managed to make an electric motor using the 9 volts battery because I didn't have neodymium magnet that could stick to the side of the 1.5 V battery, but it could to the 9 Volt one. It was more complicated than the one you made in the video but in the end mine works too, but the video was pretty useful too, I wouldn't have been able to make one without your video so thank you!
Why do you have to sand off the ends of the copper wire? Why do you need the insulation of the wire to be sanded off? Shouldn't the electricity of the battery be transferred and conducted from the copper?
The wire is covered in a very thin layer of insulation that will block electrical current from flowing. In order for electricity to flow where the wire touches the paper clip, you need to remove the insulation from the wire.
We don't recommend using a 9V battery for this project. The + and - contacts of a 9V battery are on the same end, so you can't follow the exact same directions to physically assemble the motor. The 9V battery's voltage is also much higher (9V instead of 1.5V) so you may burn out the very thin wire.
Hi - yes, this project should work if you combine two batteries in series, but you need to be careful not to burn out the thin wire. You should only run the motor for short periods of time.
Hello is it okay if i use random battery 😢 and i always test it doesn't rotated and i have neodymium magnets but it doesn't work out what should i do my project will pass next week and i haven't finished yet
Hi - if by "random battery" you mean a battery you just had laying around, it's important to use a fresh battery for this project. Please see the written instructions on our website linked in the description for an FAQ and troubleshooting information.
Neodymium magnets are much stronger and this project probably won't work without one. You usually can't buy neodymium magnets in person but they are available online.
If you are a student doing a K-12 science project, you can ask for help in the Ask an Expert forums on our website, www.sciencebuddies.org, and we can help you troubleshoot.
You can experiment with other magnets and batteries for a science project. We have not tested all possible combinations, so cannot guarantee which ones will work.
20AWG wire is pretty thick - thicker wire has less resistance so current can flow more easily, but it is also heavier. It is hard to predict so in this case the best approach is to test it and find out!
The magnet just pulls the wire wherever it's placed. How can it possibly rotate? There is nothing to push it the other way. To me it just gets stuck in one position and if I give it a push, it gets stuck again. I guess maybe I used too thick of a wire or too big of a magnet but so far I'm completely resigned.
@@mahisiyani7152 ring magnets and bar magnets will work but a horseshoe magnet would be trickier. With a horseshoe magnet, you'd need to have the ends of the magnet of opposite sides of the coil so the magnetic field is uniform
The wire needs to rotate to create an alternating electrical current, since insulation is only sanded off part of each end of the wire. If the wire was stationary you would have a constant current so the motor would not work.
You just need something that is conductive metal and not coated in plastic or another insulator. Paper clips may be easier to bend into the proper shape than safety pins.
If mine wasn't working, is it maybe because my magnet wire is thicker than yours? 'Cuz its heavier to hold the shape & the fact that it is 10 loops. My grade depends on this huhu & this is our performance task.
There are many factors that can affect the performance of this motor. The exact wire gauge is not critical, but we have not tested it with a wide range of wire thicknesses.

Does looping the ends around cause reduced magnetic field intensity?
theoretically, if you were to use outlet instead of battery. would it be spinning extremely super powerfully fast?
We cannot emphasize this enough - DO NOT PLUG THIS INTO A WALL OUTLET. This creates a severe risk of fire and electrocution.
Can we use other magnet
You need a neodymium magnet for this project to work, but the exact size is not critical.
You think 26 gauge could work?
You might be able to get it to work, but you might need to experiment with the number of coils instead of following our directions exactly.
@@Science.Buddies It works with 7 or 8 coils, thanks for the tutorial

Well made video thanks
I wonder if the wire I used is wrong, or the magnet, does the wire need to stick to the magnet even if it is not attached to the battery? mine doesn't stick.
Copper is not ferromagnetic so it will not be attracted to the magnet when there is no current flowing through it.
It's great
I am using normal magnet will it work? And I am taking copper wire from a cable. Will it work? And it will be thin wire. Will it work

Question: What kind of wire?
We recommend 28 or 30 AWG enameled magnet wire for this project (included in the kit linked in the description).
Don’t do this you can actually cause the battery to combine the positive and negative electrical current, which will make the battery get really hot and explode
Is it alright to use a normal magnet?
You need to use a neodymium magnet for this motor to work, normal magnets won't be strong enough.
Does it really need to be coiled 10 times?
We haven't tried it with fewer coils, but that would make a great science project!
The magnetic field generated will be lesser with fewer coils, so it wouldn't be as effective. The more coils the better
Make it 50 or 100 for more speed
Yes
what happens when you change out the battery for a AA4 or a C4?
Does the diameter/thickness of the wire matters? Mine is 0,1mm and idk if that's a problem
We have not tested it but this project should work with a range of wire thicknesses around 28-30AWG. If the wire gets too thick then it gets harder to bend, if it gets too thin then it won't be stiff enough to support its own weight.
Alright, I got a thicker wire though. By the way, what happens if I accidentally sand both ends fully? Is there any way to solve that? Or that doesn't matter?
It's important that each end only be half-sanded. If you sand them fully you'll need to cut the wire and start over.
@@Science.Buddies Ok, I got it. One last thing, does the item you use to make the coil matters? Im using a pencil/pen instead of a marker so the coil will be kinda smaller

We recommend using neodymium magnets for this project due to their stronger magnetic fields.
Now here's my question. What if you made the wire stationary but let the magnet rotate. Would there still be movement?
The wire needs to rotate to create an alternating electrical current, since insulation is only sanded off part of each end of the wire. If the wire was stationary you would have a constant current so the motor would not work.
