Answer:
Electromagnets have the main benefit of manipulating their magnetic pull strength – both by turning the magnet on or off and by adjusting the current. They also feature greater pull strength than permanent magnets. Some estimates place the largest electromagnet at 20 times stronger than the strongest permanent magnet.
An electric bell uses an electromagnet which is not a permanent magnet.
