Answer:
Electric bell
An electric bell is a mechanical or electronic bell that functions by means of an electromagnet. When an electric current is applied, it produces a repetitive buzzing, clanging or ringing sound. Electromechanical bells have been widely used at railroad crossings, in telephones, fire and burglar alarms, as school bells, doorbells, and alarms in industrial plants, since the late 1800s, but they are now being widely replaced with electronic sounders. An electric bell consists of one or more electromagnets, made of a coil of insulated wire around an iron bar, which attract an iron strip armature with a clapper. When an electric current flows through the coils, the electromagnet creates a magnetic field which pulls the armature towards it, causing the hammer to strike the bell.
Answer:
The working of an electric bell is based on magnetic effect of electric current.
Explanation:
Working:-
The switch is pressed and current flows through the circuit.
The electromagnet is powered and generates a magnetic field that attracts the iron strip towards it.
The striker strikes the gong (bell).
When the striking arm strikes the gong, the contact is broken and current stops flowing through the circuit.
This causes the electromagnet to lose its magnetic field.
The connected spring arm returns the striker to its original rest position.
The contact is restored and current flows through the circuit (provided the main switch is still pressed).
The process is repeated from the beginning.
