When the bell is pressed the contact screw comes in contact with the iron strip and the circuit is complete .
The current starts flowing through the coil.
The electromagnet gets magnetised ant the soft iron armature gets attracted towards the electromagnet. The movement of the hammer causes the hammer to hit the gong.
This movement beaks the circuit so that the current stops flowing and switches of the electromagnet.
The spring pulls the armature back to it's original position , the circuit is remade and the process starts over again .This is how the bell rings.

Is an electric bell a permanent magnet?
An electo-magnet is used in an electric bell.
Why in an electric bell the electric current stops again and again?
The electric bell and the electric current stops over and over again because of the fluctuations in voltages.
In electric bell electric energy is converted into which type of energy?
In electric bell, electrical energy is converted int sound energy.
Explain how water and wind can be harnessed to generate electricity?
They both power turbines which rotate to generate electricity. A turbine works the same way as an electric motor.
Explain with the help of diagram how free electrons and hole contribute to electric current?
explain with the help of diagram how free electron and hole contribute to electric curent
How do electric bells use electromagnets?
When an electric bell is operated, a current pass through an electro-magnet intermittently. The plunger moves back and forth due to intermittent magnetic operation. The moving plunger or lever connected to it hits a metallic body intermittently to ring the bell. The movement of plunger itself cuts off and cuts in the electric circuit intermittently.
Is an electric bell a permanent magnet?
An electo-magnet is used in an electric bell.
What is an electric bell used for?
it is like a door bell
In an electric bell the electric current stops again and again?
The electric bell and the electric current stops over and over again because of the fluctuations in voltages.
Why in an electric bell the electric current stops again and again?
The electric bell and the electric current stops over and over again because of the fluctuations in voltages.
What are the parts of electric bell and its function?
A mechanical bell that uses electromagnets is called an electric bell. The parts of the electric bell are spring, hammer, gong, armature, armature rod, and electromagnet. The electric bell functions are different on account of there being different types of electric bells and different means of using them.
