An electric bell works with the principle of working of electromagnetism. When the switch is pushed on, the circuit gets completed and the current starts flowing through the U-shaped electromagnet which creates a magnetic field in the core. This attracts the iron armature. When the armature moves towards the electromagnet, the hammer strikes the gong and the bell rings.
