# What is induced current explain briefly?

## What is induced current explain briefly?

Current produce in a conductor due to change in magnetic flux through the region is called induced current. Magnetic flux is product of magnetic field and area of Cross scection. Like current produce in generator is induced current.

## What does induced current depend on?

The magnitude of the induced current depends on the rate of change of magnetic flux or the rate of cutting of the magnetic field lines.

What is the value of induced current?

Hence, the value of induced current produced in a circuit depends on the following factors: number of turns in given coil. area of each turn in given coil. rate of change of magnetic field.

What is induced current explain briefly two different ways to induce current in a coil?

If a coil is moved rapidly between the two poles of a horseshoe magnet, then an electric current is induced in the coil. If a magnet is moved relative to a coil, an electric current is induced. By keeping it stationary and rotating a magnet inside it, the current in the coil can be induced.

### How do you calculate induced current in a magnetic field?

The induced emf is ε = – d/dt (BA cos θ). The magnitude of the magnetic field can change with time. The area enclosed by the loop can change with time. The angle between the magnetic field and the normal to the loop can change with time.

### What are the three factors that determine the amount of induced current?

Electromagnetic induction is when a voltage is created by passing a conductor through a magnetic field….The size of the voltage can be varied by three factors:

• The size of the magnetic field.
• The active length of the conductor.
• The speed at which the conductor passes through the field.

What is induced current proportional to?

No matter how the variation is achieved, the result, an induced current, is the same. The strength of the current will vary in proportion to the change of magnetic flux, as suggested by Faraday’s law of induction.

Is induced current the same as emf?

Closing and opening the switch induces the current. It is the change in magnetic field that creates the current. More basic than the current that flows is the emf that causes it. The current is a result of an emf induced by a changing magnetic field, whether or not there is a path for current to flow.

## How do you increase the induced current in the coil?

The magnitude of the induced current can be increased by:

1. Taking the conductor in the form of a coil of many turns of insulated wire.
2. Increasing the strength of the magnetic field used.
3. Increasing the rate of change of magnetic flux associated with the coil.

## What are the three different ways to induce current in a coil?

Solution : The current in a coil can induced by the following ways: (i) By rotating the coil in the magnetic field between the poles of U-shaped magnet. (ii) By keeping the coil stationary and moving a magnet inside it. (iii) By changing the current continuously in an another coil kept near it.

How can the magnitude of the induced current be increased?

The magnitude of the induced current can be increased by: Taking the conductor in the form of a coil of many turns of insulated wire. Increasing the strength of the magnetic field used. Increasing the rate of change of magnetic flux associated with the coil.

How is induced current related to induced emf?

An induced current is produced by a changing magnetic field. There is an induced emf associated with the induced current. A current can be produced without a battery present in the circuit. Faraday’s law of induction describes the induced emf.

### Does induced current depend on resistance?

From the formula, it is evident that the induced EMF does not depend on the resistance of the coil or wire. However, if the induced EMF produces a current, then that produced current will depend on the resistance of the coil or wire.

### What is induced current?

Induced Current. A current can be induced in a conducting loop if it is exposed to a changing magnetic field. This change may be produced in several ways; you can change the strength of the magnetic field, move the conductor in and out of the field, alter the distance between a magnet and the conductor, or change the area…

How do you determine the direction of an induced current?

The direction of the current can be determined by considering Lenz’s law, which says that an induced electric current will flow in such a way that it generates a magnetic field that opposes the change in the field that generated it. In other words, if the applied magnetic field is increasing, the current in…

What determines the induced current in a magnetic loop?

A current is also induced if the area of the loop changes, or if the area enclosing magnetic field changes. So it is the change in magnetic flux, defined as that determines the induced current.

## Does the strength of an induced current vary with magnetic flux?

No matter how the variation is achieved, the result, an induced current, is the same. The strength of the current will vary in proportion to the change of magnetic flux, as suggested by Faraday’s law of induction.
