Clearly explained, thank you. We know that induced eddy current in the aluminium plate have both levitation and drag effect on the applied magnetic field. How can we keep the levitating effect of eddy current and eliminate the drag effect for a (Magnetic levitation) application?
🔴Either something WRONG or something I don’t understand it.. How an aluminum reacts to magnets, does it got an update? The other thing is that a magnet suppose to attract metals not the opposite. Any clarification?
❤do u have any video demo of An huge Magnet fly by your Carbon fiber plate / Graphite plate / Graphine plate above & which one will fly off the Fastest.!!😊
Imagine graphene would be interesting in your initial testing. Graphene oxide on the other hand is magnetic. I suspect advancements in eddy current as new materials get explored.
Yes, but you have to consider that the conductivity is much lower for porous samples. We have customers which measure sintered products to track the production quality.
Aluminium is not magnetic, you are absolutely right in that. But aluminium is a conductor, and when a conductor is subjected to a changing electric field, it will create a current of its own, and when a current flows a magnetic field is build up. Yeah electromagnetism is weird. There are many great experiments on UA-cam showing this, search for "magnet in a copper tube" to see what I mean. Cheers
The moving magnet generates eddy currents in the material and the eddy currents create a field against the field of the magnet. Now both have the same field direction and repel each other, like two magnets.
The whole principle explained in very easy way to visualise. Thank you very much
I highly grateful for your explanation Sir!
Love from India! 🙏🙏🙏🙏
Incredible video!!!!💯💯💯 Im 47 and in a&p school rn. Doing this today in the shop and want to be prepared.
You are so humble, it's interesting to understand your Videos
Thank you sir, you're a great teacher ❤
Really great explanation, thanks very much.
Clearly explained and a little funny with the woah! Nice diagrams too. You are a very good teacher!

Great work Manfred!
Thank you for this video!!! Helped me with my studying
Thank you for this efficient explanation
Explained the topic really well👏
Sir good morning, i would like to ask about near field tube testing if what is the formula of it's depth penetration.thank you sir

Any clarification?
Can eddy current measure coating (Cr, Ni, Cu) over metallic (Brass, Zinc, Stainless Steel) substrates?
this is what i needed
Can eddy current measure paint thickness over metallic (Brass, Zin, Stainless Steel) substrates?
Can eddy current measure anodized coating thickness on Aluminum substrate?
Please include the skin effect,depth of penetration and lift off factor in eddy current testing so as to develop a comprehensive presentation.
Can Eddy Current measure paint thickness over plastic substrates?
thank you for the knowledge
Very well explained
I'm bored at work playing with Neodymium magnets and different metals like aluminum and brass. So cool

Hi Manfred,
great video! I was wondering. How strong is the Magnet you use in the intro? In Kg.
Bye
80kg
Finaaaaly i get it. Thanks!
Eddy current dependent or independent of original field?
what does the schematic of the circuit look like?
Thank you
Is it possible to reliably measure the conductivity of a porous sample with this method?
Yes, but you have to consider that the conductivity is much lower for porous samples. We have customers which measure sintered products to track the production quality.
nice video
😢Can u put Carbon fiber inside too. Will it works too?? Video have!!😊
Bear in mind, aluminum is not magnetic..Maybe the one you are using for the demonstration is an aluminum alloy already.

Good . Thanks 🙏🙏🙏🙏🙏
electric current always surrounded by magnetic fields, right?
Correct
Y GIVE ME GREAT way TO explanation ET
Isn't aluminum non-magnetic?
1:19 see in 0.25x speed magnet touching Aluminum and thats why it happened 😂
My man slammed that sh*t 😂
👍👍👍👍👍👍👍
thank yoU!
2:13 can you explain this
But how does aluminium move by magnet...?
The moving magnet generates eddy currents in the material and the eddy currents create a field against the field of the magnet. Now both have the same field direction and repel each other, like two magnets.
bro did not do the thug shaker 😿
GRAZIE
aluminium is not magnetic?
Exactly - only iron, nickel and cobalt are ferromagnetic at room temperature - ( en.wikipedia.org/wiki/Ferromagnetism )
Paramagnetic
Guys exposed check 1 min 13 sec in slow

It's a-lu-mi-num, not a-lu-mi-nium. Otherwise good video.
Aluminium is the British spelling, both are fine
@@water5210 Is it spelled that way in the dictionary?
@@nathanrice1796 yes
Apparently we've been saying it wrong since 1990
Can Eddy current measure coating (Cr, Ni, Cu) over plastic substrates?
Can Eddy Current measure coating thickness over coating (Cr, Ni, Cu) thickness over ferrous substrates?
👍👍👍👍
