As mentioned above, a doorbell works on the principle of electromagnetism. The basic component of a doorbell is an electromagnet. An electromagnet is a coil of wire wrapped around a little piece of magnetic metal. When the current passes through the wire, it makes a magnetic field around the wire.
When the button is pressed, the electric current circuits complete by passing through the internal electromagnet of the doorbell. A doorbell is a low voltage small gadget. This means that even if there is a low voltage of electricity, it can operate. A transformer is an important part of a doorbell that transforms the traditional household voltage of 120 V into a lower voltage.
