Question

what magnet will you choose Among permanent magnet and electromagnet for industrial purpose?

Answer 1

electromagnet is best for industrial purpose

Answer 2

Here is your answer :

⇒ The permanent magnet does not have electric current flow through it.

⇒ Electromagnets are made by passing electric current through it.

⇒ The strength of the magnetic field in permanent magnets cannot be changed.

⇒ The strength of the electromagnets can be changed by changing the amount of current in the magnet.

⇒ The direction of the magnetic field cannot be changed.

⇒ The direction of magnetic field can be changed in electromagnets.

⇒ The polarity of permanent magnets cannot be changed.

⇒ The polarity of the electromagnets can be changed.

Thus electromagnet is better !
