Which of the following uses the principle of mutual induction?

transformer
Complete answer: A transformer is a device that operates on the principle of mutual induction.

What is mutual inductance explain?

mutual inductance. noun. a measure of the mutual induction between two magnetically linked circuits, given as the ratio of the induced electromotive force to the rate of change of current producing it. It is usually measured in henriesSymbol: M, L 12 Also called: coefficient of mutual induction.

What is application of mutual induction?

The applications of mutual inductance are, Transformer. Electric Motors. Generators. Other electrical devices, which work with a magnetic field.

What is the working principle of transformer?

Principle – A transformer works on the principle of mutual induction. Mutual induction is the phenomenon by which when the amount of magnetic flux linked with a coil changes, an E.M.F. is induced in the neighboring coil.

Which device works on the principle?

An electric generator is a machine which generates electricity by using the principle of electromagnetic induction.

What is mutual induction describe an experiment to demonstrate it?

In the experiment, a coil denoted by C1 is connected to a galvanometer, and a bar magnet is placed near to it as shown in the figure. When the bar magnet is held stationary, the galvanometer does not show any deflection. This induced emf causes the electric current to flow in the coil and through the galvanometer.

What is motor principle?

An electric motor works on the principle that when a rectangular coil is placed in a magnetic field and a current is passed through it, a force acts on the coil which rotates it continuously. Hence, electrical energy is converted into mechanical energy.

Who gave the principle of electromagnetic induction?

Michael Faraday
Electromagnetic or magnetic induction is the production of an electromotive force across an electrical conductor in a changing magnetic field. Michael Faraday is generally credited with the discovery of induction in 1831, and James Clerk Maxwell mathematically described it as Faraday’s law of induction.

What works on principle of electromagnetic induction?

An electric generator works on the principle of electromagnetic induction.

How does mutual induction work?

Mutual inductance is where the magnetic flux of two or more inductors are “linked” so that voltage is induced in one coil proportional to the rate-of-change of current in another. A transformer is a device made of two or more inductors, one of which is powered by AC, inducing an AC voltage across the second inductor. If the second inductor is connected to a load, power will be electromagnetically coupled from the first inductor’s power source to that load.

What does induction, coefficient of mutual mean?

Coefficient of mutual induction IP is the current in coil P and φs is the magnetic flux linked with coil S due to the current in coil P. where M is a constant of proportionality and is called the coefficient of mutual induction or mutual inductance between the two coils. IfIP = 1A, then, M = φs

What is the unit for mutual inductance?

The International System (SI) unit of mutual inductance is the henry, the same as the unit of self-inductance. The same value is obtained for a pair of coils, regardless of which coil is the starting point.

What is their mutual inductance?

Mutual inductance occurs when the change in current in one inductor induces a voltage in another nearby inductor. It is important as the mechanism by which transformers work, but it can also cause unwanted coupling between conductors in a circuit.
