An artificial magnet is a magnetized piece of iron (or other magnetic material). Artificial magnets are required because natural magnets have odd and irregular shape and they are not magnetically very strong. Artificial magnets can be given desired shape and made very strong.
Which magnet will you choose among permanent?
Answer Expert Verified
1) Electromagnets are generally stronger than permanent magnet. Hence, work load would be reduced by electromagnets. 2) Electromagnets can be switched on and off when needed. However, permanent magnets can’t be switched off.
