Question

Which metal is used to make a permanent magnet?

Answer 1

1. Ferromagnetic materials like Cobalt, Nickel, and Iron are used in making a permanent magnet.
2. Ferromagnetic materials are those materials whose domains become aligned to produce a strong magnetic field.
3. These substances are strongly attracted by a magnet.
4. In domains of ferromagnetic substances, they have a permanent dipole moment.
5. This dipole moment is very large in ferromagnetic substances and in the same direction as a magnetic field.
6. Thus, Ferromagnetic materials like Cobalt, Nickel, and Iron are used in making a permanent magnet.
