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.

Which jobs use electromagnets?
Probably the most important use is in the electric generator. They are used in metal detectors, and speakers. In generators they are used to generate a constant charge. In metal detectors they are used as a sensor; where the field is changed by metals in the ground. And in speakers they are used in a to and fro motion on a diaphragm to make sound.
The discovery of electromagnets led to the invention of electric motors.?
Yes it did
What are the components of electricity?
Electricity is the interaction of many components. These include electric charges, electric fields, electric potentials, electric currents, and electromagnets.

What are the uses in the electromagnets?
Electromagnets have several uses. They are used in cranes to pick heavy metal objects, to lift tiny metal scraps from wound by doctors, motor and generators, electric bells, loudspeakers, etc.
Where do you find electomagnets in your home?
you find electromagnets in electric bells,telephone,t.v,radio sets all sound systems and sometimes in fans.
What industry use electromagnets?
Since electromagnets are used in most large electric motors,the answer is almost all industry.
Do telephones telegraphs and electric motors all use electromagnets?
phones and electric motors definitely do!
Where use electromagnets?
Inside of electric motors are electromagnets and permanent magnets. In a metal junk yard large electromagnets are used to pick up metal. In MRI's large electromagnets are used for imaging.
Where are electtromagnets used?
Electromagnets are commonly found in various everyday electronics that have moving parts. Some examples are electric windows, radio speakers, cranes to lift heavy materials, electric bells and microphones.
Why don't we use permanent magnets in electric bell?
permanent magnets are not used in electric bells because they do not make the bells to ring well
Uses of electromagnets in everyday living?
Electromagnets play vital roles in everyday life. They power electric motors in appliances, produce sound in speakers, and enable magnetic door locks for security. Medical imaging devices like MRI machines rely on electromagnets, and maglev trains use them for propulsion. Additionally, electromagnets are utilized in scrapyard cranes for efficient lifting of metallic objects. These applications demonstrate the widespread importance of electromagnets in modern society.
Electromagnets are the result of?
Electric currents.
What are devices that use electromagnets?
Motors Transformers Maglev trains Electric toothbrushes Induction heaters
What are the parts and its function of electr?
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.
