Question

give 10 point of permanent magnet and electromagnet​

Answer 1

Answer:

Electromagnet

When a battery is connected to a solenoid (a coil of wire is wounded around a nail), the apparatus behaves like a magnet. This is due to the magnetic field produced by the current flowing through the coil. The nail retains its magnetism until there is a current flowing through the coil, but once there is no current, the nail loses its magnetism.

You can produce electromagnets when you wound a coil of wire across an iron core. Let us now look at the differences between a permanent magnet and electromagnetPermanent Magnet

These types of magnets can retain their magnetism and magnetic properties for a longer time. Strongly magnetized hard materials make up permanent magnets. A perfect example of a permanent magnet is the Bar Magnet. This magnet widely explains the behavior of magnets. Actually, we call permanent magnets as Bar Magnets also.
