As soon as the electromagnet gets activated it would pull the hammer towards the metal to produce the sound and at the same time the electrical circuit will be broken and so the electromagnet would stop attracting the hammer and so hammer goes back and again the circuit is completed. So the cycle starts newly. Thus the electromagnet switches off and switches on the circuit successively and also makes the hammer to hit the bell.
The pushing of the doorbell closes an electric circuit. Then electric current flows through an electromagnet, and the doorbell rings.

Who invented the doorbell?
The first electric doorbell was invented by Joseph Henry in 1831. Henry was an American scientist who made significant contributions to the field of electromagnetism. His design used an electromagnet to move a metal hammer against a bell to create the ringing sound.
Did Michael Faraday invent magnetism?
No. but he used an electromagnet to make discoveries about electricity.
Did Michael Faraday invent the magnet?

When an electric current runs through a doorbell buzzer a mechanism inside vibrates back and forth and makes the doorbell work?
When an electric current passes through a doorbell buzzer, it energizes an electromagnet that activates a mechanical mechanism inside the buzzer. This mechanism typically consists of a diaphragm or a metal arm that vibrates back and forth rapidly. As it vibrates, it creates sound waves, producing the ringing sound associated with a doorbell. The process effectively converts electrical energy into sound energy.
Are Electromagnets used in doorbells?
Some doorbells have a "clapper" (a small hammer) that hits one or more bells (often tubes of metal) the action of the hitting can be initiated by an electromagnet pulling the clapper. The doorbell switch can in such an arrangement close the circuit to the electromagnet.
Why is a doorbell containing an electromagnet called a 'make and break' circuit?
A doorbell containing an electromagnet is called a "make and break" circuit because the circuit is completed ("made") when the switch is pressed, allowing current to flow through the electromagnet and create a magnetic field that attracts the doorbell mechanism. When the switch is released, the circuit is broken, stopping the flow of current and releasing the doorbell mechanism.
Does a doorbell use an electromagnet?
yes it does
What is the purpose for an electromagnet in a simple doorbell?
to produce magnetic field to move the piston of the doorbell
What is the role of an electromagnet in a doorbell?
The electromagnet pulls a plunger which then hits the bell. The action of being pulled, also breaks the power to the electromagnet, so it returns almost immediately, making the power again. This action repeats for as long as the pull push is pressed, causing the plunger to vibrate and the bell to ring.
How is an electromagnetic used in a doorbell circuit?
An electromagnet is an essential piece on a doorbel circuit. The electromagnet enables the operation of the a self-interrupting circuit. Special electromagnets called solenoids are used for doorbells with chimes.
Why is the electromagnet inside a doorbell magnetised and demagnetised alternatively?
The electromagnet inside a doorbell is magnetized when an electric current flows through it, creating a magnetic field that attracts the metal clapper to ring the bell. When the current stops, the magnetic field dissipates, demagnetizing the electromagnet and allowing the clapper to return to its resting position. This process of magnetization and demagnetization occurs repeatedly to produce the ringing sound of the doorbell.
How do electromagnet get their names?
An electromagnet is only magnetic when an electric current is run through it.
Why might an electromagnet be a good source of energy for a doorbell?
An electromagnet is a good source of energy for a doorbell because it can be activated and deactivated quickly, producing the vibrations needed to create sound in a doorbell. When an electric current passes through the coil of wire in the electromagnet, it generates a magnetic field that causes the striker to move and strike the chime, producing the ringing sound. Additionally, electromagnets are reliable and efficient in converting electrical energy into mechanical energy, making them suitable for doorbell applications.
How does the door bell make sound?
When the doorbell button is pressed, it completes an electrical circuit that activates the doorbell chime or buzzer. The chime or buzzer contains an electromagnet that moves a metal bar to strike the chime, creating the sound. The sound is amplified through the resonance of the chime or buzzer, producing the characteristic doorbell sound.
Is the doorbell used in all of north America?
Yes, most houses make use of the doorbell in north America
How does a doorbell use an electromagnet?
The electromagnet is only part of the mechinism the whole item is called a solenoid which has a magnetized rod inside the electromagnet when 24 volts is applied the solenoid springs out of the coils of the electromagnet striking the bell. When released the rod returns by use of a spring and strikes another bell. Ding, Dong.
Why is the electromagnet inside the door bell magnetised and demagnetised alternatively?
The electromagnet inside the doorbell is energized with an electric current, which magnetizes it to attract the metal chime. When the current is turned off, the magnetism is lost, causing the chime to be released. This alternating process creates the ringing sound in a doorbell.
