I tried 1.000.000 on google and I didn't find nothing. So please help me. Thank you.
Ok, but is it possible that current will show up, right?ranger said:When the magnetic domains of the iron bar (or any material in general) come under the influence of a magnetic field; they realign. Causing the iron to have more apparent magnetic properties.

And magnetism doesn't require changing magnetic field?ranger said:That would require a change in magnetic flux.

so you say that I can magnetize some iron bar without time-varying magnet, right?Archduke said:Nope. It's just magetic interaction between the magnetic fields of the domains and the magnetic field of the permanent magnet.

But are they are forced from their "own" magnetic field?ranger said:Electron motion in atoms produces the magnetic fields of permanent [ferro]magnet.
Electrons get excited when they have kinetic energy due to thermal activity or when they are influenced by a potential difference/electric field.

To magnetize an iron bar, you can use a strong magnet and rub it against the bar in one direction multiple times. This will align the electrons in the iron atoms in the same direction, creating a magnetic field.
No, only ferromagnetic materials can be magnetized. These include iron, nickel, and cobalt. Other types of iron, such as cast iron and steel, may contain these elements but their composition and structure prevent them from being magnetized.
This depends on the strength of the magnet being used and the size of the iron bar. Generally, it may take a few minutes of rubbing with a strong magnet to magnetize a small iron bar, while larger bars may take longer.
If you try to magnetize a non-magnetic material, such as aluminum or copper, it will not become magnetized. These materials do not have the necessary properties to align the electrons and create a magnetic field.
Yes, the magnetization of an iron bar can be reversed by using a strong magnetic field in the opposite direction. This can be achieved by rubbing the bar with a magnet in the opposite direction or by using an electromagnet with a current flowing in the opposite direction.
