Hey mate here is your answer》》

An electromagnet can be switched on and off to repeatedly strike the bell and release the hammer. A permanent magnet will strike the bell once and not let go.

Answer 2

No, an electric bell does not use permanent magnet.

- Electromagnets are used in electric bells because the continuous on-off sequence of the electromagnet becomes the reason behind the continuous hammering and ringing of the bell.

- If permanent magnets are used instead of electromagnet then the hammer will strike for only one  time and will be stick into the bell's which will not produce continuous hammering and ringing.
