About the removal of neodymium magnets. They are very brittle so wacking is not a good idea, espeacially with the thinner ones. What you do is get a pair of good pliers, a pair of strong hands, and then bend the plate that the magnets are atached to. They will be easy to remove, although some of the nice coating might peel off.
You might want to consider leaving the magnets in the metal, for speakers, or stuck on the metal when dealing with hard drives. With the speaker magnets, the metal acts as a shield in one direction, which can be useful for some applications and experiments, and the metal plates the hard drive magnets are stuck to can be used for mounting the magnets on non-magnetic material.

Old analog meters for measuring currents or volts work by an electromagnet pushing at a permanent magnet, but I suspect the magnet may be rather small. Magnetrons, some of the old antennas, the colorful part around the brass ring, may contain beryllium. If that part breaks and the dust is inhaled it may cause beryliosis, a rather nasty lung condition that makes for a painful way to die
This video gave me the answer to a question that I always place: how do I divide a magnet from a useless piece of metal? thanks for giving me the answer
Can you explain sir why that shiny part on metal housing from speaker magnet is so strong? It looks like gall coated metal but what is that in the center is it aluminum coated? Its nearly strong the center as bouth poles together. And the strange thing is bouth poles from other magnet are atracted to it
It was very difficult to remove the neodyme magnets because they're glued down. One of them has so much glue on it it is impossible to remove. I actually ended up breaking the magnet before I had gotten it off.
next time try bending the plate it is on with a pair of pliers, then once it is bent slide a knife between the plate and the magnet, it should come right off
I’m not sure how the magnet works between the North Pole & South Pole what’s I understand if the magnet pulled in together is the south pole if it pushed out is the North Pole maybe I got it wrong
Hi Baddy thank you for your information I can't fund ur email address also I aerdy subscribed you I have a question for you it's possible to make electricity by magnetic could you help about that thanks again and also replying me by email please 😊

Great video. Very clear and well produced. Much appreciated.
Great tips on the separation. Will have a go with some of my stash of speaker magnets, which i now know to be ceramic.
Breaking the glue seal by supporting the magnet on steel nuts worked a treat. Thx!

Thank you for a very informative presentation.

Thank you!! That was awesome advice.
Great video thank you
Thanks - best removal advice I've found
When you break the ceramic magnets for kids, sand the edges. They can be razor sharp on some magnets.
you got yourself a new subscriber

Very informative! Thank you very much!
Thankyou so much!!!! It really helped me a lot to separate the magnet from the metal. Thankyou :>

Great video, very helpful

And this is prove that we learn more from experienced people then we learn from newbies.
(y)
very helpful whats the strenght of the magnet or whats the strongest u can get
Thank you very much for your advice.

Great film! Who would have thought you could make a compass from an old speaker and a kebab stick!

heat gun
What if I take the magnet out of the speaker but leave the core inside? Will it still be useful for levitation projects?
thank you thank you thank you thank you thank you soooooooooooooooooooooooooo much this really helped me
Thank you!!!!
Hi great job can you share with me any new information please thanks 🙏
I’m not sure how the magnet works between the North Pole & South Pole what’s I understand if the magnet pulled in together is the south pole if it pushed out is the North Pole maybe I got it wrong
He looks like Captain Clarence Oveur from the movie "Airplane"...!!!
Hey I got a stupid quastion: do magnets work in space ?
Yes. Electromagnetism is a fundamental force of the entire universe.
It gives me great joy to see people learn
Thankyou sir
Thank u
How
I put speakers on my stove and heat them up to remove the magnets just don't get them too hot or you will ruin your magnets
Great
Like it
i wanna see the part where he hits the bolt in slow-mo
What a type of auseme
I thought the south would face north ???
Yes, but the geographic north pole of the earth is the magnetic south pole of the earth
doesnt always work because some have very strong glue.

Shattered my magnet
Magnetism is magnets with autism
Grazie !
