What is an electromagnet give any two applications of electromagnets?
A magnet that consists of a piece of iron or steel surrounded by a coil is known as an electromagnet. When an electric current is passed through the coil, the metal becomes magnetic. Two uses of electromagnets are as follows : In electrical devices such as in loudspeaker, electric bell, and electric motor.
How is electromagnet used in telephone?
The telephone receiver is basically an electromagnet with a U-shaped yoke having coils wound on each leg of the U. Passage of the electrical signal through the coils causes magnetic attraction of a soft-iron diaphragm supported a small distance from the ends of the U.
What is electromagnet write its application?
Electromagnets are used in millions of devices around the world, from hard disk drives and MRI machines, to motors and generators. A motor takes electrical energy and uses a magnet to turn that electrical energy into motion. Motors can be found in cars, washing machines, food processors, fans, and elevators.
How electromagnets making your life easier?
Inventors have harnessed electromagnetic forces to create electric motors, generators, MRI machines, levitating toys, consumer electronics and a host of other invaluable devices that you rely on in everyday life.

How do headphones use electromagnets?
More specifically, headphones convert electrical energy (audio signals) into mechanical wave energy (sound waves). Many headphones do so via electromagnetic induction. Electromagnetic induction states that a voltage will be produced across an electrical conductor in a changing magnetic field.
Does a television use electromagnets?
Electromagnetism plays an important role in a television. It is used for electromagnetic deflection and Detection yoke. Electromagnets generate the electron beam and cause it to scan the picture area.
What is another application of electromagnets How does it work?
Electromagnets are also used for industrial applications, such as magnetic lifters that use magnetic attraction to lift heavy objects or magnetic separators that are responsible for sorting ferromagnetic metals from scrap metal. And last, but certainly not least, there is the application of maglev trains.

Electromagnetism serves as a basic principle of working for many of the home appliances in household applications. These applications include lighting, kitchen appliances, air conditioning systems, etc. The most dominant use of power in homes as well as commercial buildings is lighting systems.
What is an electromagnet and its uses?
An electromagnet can be defined as a magnet which functions on electricity. Unlike a permanent magnet, the strength of an electromagnet can be changed by changing the amount of electric current that flows through it. If the current flow is cut, the property of magnetism ceases to exist.
Does a school bell use an electromagnet?
Process of the working of an electric bell 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.
