# What is the example of mutual induction?

## What is the example of mutual induction?

If two coils of wire are brought into close proximity with each other so the magnetic field from one links with the other, a voltage will be generated in the second coil as a result. This is called mutual inductance when voltage impressed upon one coil induces a voltage in another.

What do you meant by mutual induction?

Mutual induction is defined as the property of the coils that enables it to oppose the changes in the current in another coil. With a change in the current of one coil, the flow changes too thus inducing EMF in the other coil. This phenomenon is known as mutual induction.

What are the applications of mutual induction?

The applications of mutual inductance are, Transformer. Electric Motors. Generators.

### Which device is working using mutual induction?

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

What is inductance Byjus?

The inductance of an inductor is the tendency of the electrical conductor to resist any change in the current flowing through it. A magnetic field is created around the conductor due to the flow of electric current.

How is EMF created?

In nature, emf is generated when magnetic field fluctuations occur through a surface. In an electrical generator, a time-varying magnetic field inside the generator creates an electric field via electromagnetic induction, which creates a voltage difference between the generator terminals.

#### What is the advantage of mutual inductance?

A transformer is a device which uses the phenomenon of mutual induction to change the values of alternating voltages and currents. In fact, one of the main advantages of a.c. transmission and distribution is the ease with which an alternating voltage can be increased or decreased by transformers.

How is emf created?

What is SI unit of inductance?

The henry (symbol: H) is the SI derived unit of electrical inductance. If a current of 1 ampere flowing through a coil produces flux linkage of 1 weber turn, that coil has a self inductance of 1 henry.

## What is capacitor BYJU?

The capacitor is a device in which electrical energy can be stored. It is an arrangement of two-conductor generally carrying charges of equal magnitudes and opposite sign and separated by an insulating medium.

What is N in inductance?

The inductance of a coil of wire is given by. Solenoid length cm with N = turns, Coil radius r = cm gives area A = cm2.

Is EMF equal to voltage?

Electromotive force (EMF) is equal to the terminal potential difference when no current flows. EMF and terminal potential difference (V) are both measured in volts, however they are not the same thing. EMF (ϵ) is the amount of energy (E) provided by the battery to each coulomb of charge (Q) passing through.

### What are the applications of mutual inductance?

Applications of Mutual Inductance The principle of mutual inductance is followed in various electronic devices. Some of them are as follows; Motors Note the inductors (Lfand La) in the dc motor circuit that are mutually inducted. Transformer Also Read:Transformer Generators The induced EMG in a generator by electromagnetic induction is shown below.

What is the coefficient of mutual induction?

The coefficient of mutual induction – mutual inductance depends only on the geometrical factor of the two coils such as the number of turns, radii of two coils and on the properties of a material medium such as magnetic permeability of the medium surrounding the coils. Also Read:Electromagnetic Induction

What is meant by mutual induction between circular coils?

(1) Mutual induction between circular coils. Consider two circular coils (closely packed) coaxially placed to each other. The coil with a larger radius has N1turns and that with smaller radius has N2turns. Also, assume that R1>> R2.

#### What is mutual inductance in JEE?

JEE Notifications NEET Notifications JEE IIT JEE Study Material Mutual Inductance Mutual Inductance Mutual inductance is the main operating principle of generators, motors, and transformers. Any electrical device having components that tend to interact with another magnetic field also follows the same principle.
