Question

Which type of magnet is used in an electric bell?

• A. Bar magnet
• B. Cylindrical magnet
• C. Electromagnet
• D. Horseshoe magnet

Answer 1

The correct option is C Electromagnet

In an electromagnet, the magnetic field is generated with the help of electric current. Electromagnets are temporary magnets i.e. they lose their magnetic properties as soon as the flow of current is stopped.
Hence these types of magnets are best suitable for an electric bell as their magnetism appears as soon as the electric current passes through them and magnetism disappears as soon as the flow electric current is switched off.
