Question

what is permanent magnet​

Answer 1

Answer:

1. A magnet that retains its magnetism after removal of the magnetizing force.

2. Permanent magnets are materials where the magnetic field is generated by the internal structure of the material itself.

3.  But in certain materials, called ferromagnets, all the spins and the orbits of the electrons will line up, causing the materials to become magnetic.

4. This would be your normal iron, cobalt, nickel.

Answer 2

• A magnetic field is produced by a magnet.
• A magnetic field is invisible.
• A magnetic field is a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc.
• A magnetic field is used to attract or repel other magnets.
• A permanent magnet is made from a material that is magnetized.
• A permanent magnet creates its own magnetic field.
• Materials that are strongly attracted to a magnet, are called ferromagnetic.

Hence, the permanent magnet is used to attract or repel other magnets.
