How does an electric doorbell work?

Answer 1

when the doorbell button is pressed it closes a circuit and energizes the coil of a solenoid. The solenoid coil then causes a hammer to shoot out from the coil and strike a the doorbell chime.

Answer 2

Electric bells work by use of an electronic magnet. When the hammer hits the bell the magnet is turned off. When the hammer returns to its normal position the magnet re-activates making the hammer hit the bell. This cycle will repeat until the electric current supplying the magnet is broken.

Answer 3

when you push the switch of the bell the electicity is passed to the bell. there is a little coil running around a metal piece in site the bell. when the AC (alternate current) passess through the coil it creates the magnetic field and tries to attract the little hammer towards itself. The hammer is kept in tension so that it always tries to move away from the metal piece. the continuous attraction of the metal piece and the pull back action of the hammer results in a vibrating motion of the hammer. the head of the gammer is allowed to touch the edge of the bell slightly. the continuous touching (hammering) results in the producion of the sound. and this is the way the electric bell works....

Answer 4

When a doorbell button is pressed, it copletes a circuit and you hear the loud ring. A doorbell has a number of components that makes it. It has electricity source, so when you press it, current flows from the elec. source through the contact between the box terminal and the striker terminal. When the electromagnt attracts the striker, two things happen. The striker hits the bell and the striker terminal gets pulled away from the box terminal. This breaks the circuit. When the circuit is broken, the magnetism goes away. The striker returns to its place. That brings the terminals back together, so the circuit is complete. The whole process starts over. The bell rings as long as you hold the button.

Answer 5

The doorbell button sends a transmitter, which sends a radio signal to the receiver on the inside of your home or building. This causes the doorbell to sound.
