# Question: What Happens When A Current Carrying Wire Is Placed In Magnetic Field?

## What happens when a current carrying conductor is placed in a magnetic field Class 10?

When a current carrying conductor is placed in a magnetic field,the conductor experiences a force.

(6) Reverse the direction of current flowing through the rod and observe the direction of its displacement.It is now towards the right..

## What factors affect the force on a current carrying conductor in a magnetic field?

The magnitude of the force on a current carrying conductor increases when the strength of the magnetic held is increased. The magnitude of the magnetic force also depends on the length of the wire in the magnetic field. The longer the wire in the magnetic field, the larger the force on the wire as shown in Figure.

Electric current produces a magnetic field. This magnetic field can be visualized as a pattern of circular field lines surrounding a wire. … Magnetic Field Generated by Current: (a) Compasses placed near a long straight current-carrying wire indicate that field lines form circular loops centered on the wire.

## How will this force change if current in the conductor is increased?

The expression of magnetic force id defined as F = CIL Sin theta. (a) Hence, as the current, I in the conductor increases, the force also increases. … (d) When the direction of the magnetic field remains constant and the current is reversed, the direction of the force changes due to the variation of the angle, theta.

## What kind of magnetic field is produced by a solenoid?

Answer. Solenoid consists of a length of insulated wire coiled into a cylinder shape. Current in solenoid produces a stronger magnetic field inside the solenoid than outside. The field lines in this region are parallel and closely spaced showing the field is highly uniform in strength and direction.

## What is the right hand rule for electromagnetic induction?

Fleming’s right-hand rule (for generators) shows the direction of induced current when a conductor attached to a circuit moves in a magnetic field. It can be used to determine the direction of current in a generator’s windings.

## Why does changing magnetic field induce a current?

According to Lenz’s Law , Lenz’s law states that the current induced in a circuit due to a change or a motion in a magnetic field is so directed as to oppose the change in flux and to exert a mechanical force opposing the motion. … Thus the changing magnetic field creates an EMF which in turn induces an electric current.

## What will be the direction of induced current?

An induced current has a direction such that the magnetic field due to the induced current opposes the change in the magnetic flux that induces the current. for the given loop (this vector is always normal to the loop!)

## What is the direction of induced current in coil?

As seen from the side of the approaching magnet the current inside the coil should be clockwise so that the induced magnetic pole on the left side of the coil is ‘south’ and it tends to repel the approaching magnet(Lenze’s Law), hence the magnet’s field inside the coil points from right to left(opposite to the …

## What happens to a current carrying wire in a magnetic field if the current is reversed?

What happens to a current-carrying wire in a magnetic field if the current is reversed? The wire will be deflected perpendicular to the magnetic field in the opposite direction. … The wire will be deflected perpendicular to the magnetic field in the same direction.

## What happens when a current carrying coil is placed in a magnetic field?

If a current carrying coil is placed in a magnetic field then the coil will experience a turning and twisting force on it.. … It experience the Lorentz force unless and until the angle between the current and magnetic field line is zero degree…

## When a current carrying conductor is placed in a magnetic field?

When a current-carrying conductor is placed in a magnetic field, a mechanical force is exerted on the conductor which can make the conductor move.

## Does a current carrying coil produce uniform magnetic field?

No, magnetic field produced due to a current carrying circular coil is not uniform. However, it may be considered as uniform at the centre of the circular coil.

## What happens if there is no change in the direction of current in the coil of wire which is kept in uniform magnetic field?

If there is no change in the direction of the current in the coil of wire, it shows the property of the magnetic force acting on the moving charged particles. The free electrons move towards the positive end of the conductor with some velocity. As a result of this, magnetic force acts on them.

## What is the direction of the current if the magnetic flux is increasing?

By convention, the direction in which current would have to flow around the loop in order to increase the magnetic flux linking the loop is termed the positive direction.

## Can we obtain a region of uniform magnetic field by using single current carrying narrow circular coil?

No, magnetic field produced due to a current carrying cirular coil is not uniform. However, it may be considered as uniform at the centre of the coil.

## Why is there a magnetic field even when there is no current?

Any electrical wire that is charged will produce an associated electric field. This field exists even when there is no current flowing. The higher the voltage, the stronger the electric field at a given distance from the wire. … The higher the current, the greater the strength of the magnetic field.

## What does eddy current mean?

Eddy currents (also called Foucault’s currents) are loops of electrical current induced within conductors by a changing magnetic field in the conductor according to Faraday’s law of induction. Eddy currents flow in closed loops within conductors, in planes perpendicular to the magnetic field.

## Why is there no current produced when the magnetic field and the coil is in the same plane ie parallel )?

There is no change in the magnetic flux. Why is there no current produced when the magnetic field and the coil is in the same plane (i.e., parallel)? … Since there is no perpendicular area through which the magnetic field is passing, no magnetic flux is possible.

## When you immerse a current carrying coil in a magnetic field is there a net force on the coil?

The Torque on a Current Loop A uniform magnetic field exerts no net force on a current loop but it does exert a net torque. Let’s say the magnetic field is in the plane of the loop and is parallel to two sides.

## What is Faraday’s law formula?

The equation for the EMF induced by a change in magnetic flux is. EMF=−NΔΦΔt EMF = − N Δ Φ Δ t . This relationship is known as Faraday’s law of induction. The units for EMF are volts, as is usual.
