Magnetizing and Demagnetizing - explained simply and clearly

[@humanskull182]

I’m very glad he put real and virtual at the bottom to let us know which is which. Jokes aside. Amazing video and really easy to understand

[@williampersson4373]

thank you, this was very helpful. short, easy to understand and we did not have to wait for 10 minutes to wait for you to get to the main topic, i wish all explanation videos were like this

[@jacobras]

This really was explained simply and clearly. Great video!

[@bhaktisutar4744]

The animation explains it at its best level 🤩

[@biggiesmalll]

Excellent video

Do I understand this correctly? After being magnetized, could the magnetized nail then be used to magnetize something else? Basically, if you begin with one magnet, could you theoretically create a chain of magnets, magnetizing other things until every piece of ferrous metal on the planet would be magnetized? (I hope that's not too confusing. Sorry for the grammar. Just woke up.)

I am curious about the topic of “magnetisation” From what I know there are 3 methods -induction method -stroking method - and through electric current Through these 3 methods can you tell me what type of magnet each methods could create like as in permanent or temporary. I really appreciate your help!

Great video!

Is it possible to magnetize iron with an ac electromagnet like we can do with a dc electromagnet ?

[@Eagle_View_360degree]

Can you do one experiment for us.. 1. When you keep iron nail in north-south direction (for few days or few weeks).. will it attain magnetic property or not..?? Please explain

[@niupschlusselexperimente-r8019]

Great! Thanks!

And without heat, could you demagnetize the nail with the opposite pole of the magnet, provided you don't go too far and re-magnetize with opposite alignment?

[@physikdigital]

I tried to do so, but with no success. The 'best' way to demagnetize a magnetized nail is to hit the nail with a hammer

A trick: watch movies at Flixzone. I've been using it for watching loads of movies during the lockdown.

[@yahirmaximilian4322]

@Ray Bryson Yup, I have been using Flixzone} for years myself =)

[@luccafrancis4227]

@Ray Bryson Definitely, I've been using Flixzone} for since november myself :D

[@yousefreyansh3506]

@Ray Bryson yea, been watching on Flixzone} for since november myself :)

The heat? Demagnitized the nail? So heat has charge?

[@h7opolo]

Now try magnetizing both the paper clip and the nail and see how they interact for some extra fun.

Is this professor Vacheck Pthepher? The mathematician from UC Davis? If not, you sure do sound exactly like him. And same exact accient too. ...and I am a sound engineer BTW. lol...😉 🤫

[@physikdigital]

Hi. I´m not this proffessor =)

[@alchemy1]

So you used heat to demagnetize as the only way? You can not demagnetize it with the very same magnet you have? Why not?

[@krummeltv4605]

top!

[@sereyrachanasoeu1734]

When an object is magnetise can u call it a magnet?

[@physikdigital]

yes. you can.

[@sereyrachanasoeu1734]

@@physikdigital ohhh ok! Thxs! Btw I am curious about the topic of “magnetisation” From what I know there are 3 methods -induction method -stroking method - and through electric current Through these 3 methods can you tell me what type of magnet each methods could create like as in permanent or temporary. I really appreciate your help!
