# What happens when coil is perpendicular to magnetic field?

## What happens when coil is perpendicular to magnetic field?

The emf is maximum when the plane of the coil is parallel to the magnetic field as at this position the change in magnetic flux is the most and the emf is minimum when the plane of the coil normal or perpendicular to the magnetic field as at this position the change in magnetic flux is zero.

## When a coil is rotated in a uniform magnetic field about an axis perpendicular?

The correct option is a parallel to field. Explanation:i.e. angle between area vector and magnetic field is π/2 so angle between plane of the coil and magnetic field is zero So plane of the coil is parallel to the field.

## What angle is it if the plane of a coil is perpendicular to the magnetic field?

And therefore, the angle 𝜑 between the plane containing the area 𝐴 and the magnetic field is perpendicular when the torque is equal to zero, that is, when 𝜑 equals 90 degrees. Therefore, the correct answer is 90 degrees.

## Is a magnetic field perpendicular to the plane of a flat coil?

A magnetic field is perpendicular to the plane of a flat coil. Since the magnitude of the field is increasing, an emf will beinduced in the coil unless something is done to prevent it.

## When charges move perpendicular to a magnetic field?

When the velocity is perpendicular to the magnetic field, the magnetic force is perpendicular to both of them, and particle moves in circle with constant speed v.

## When a wire is moving perpendicular to a magnetic field?

If a straight conducting wire is placed in a plane perpendicular to a uniform magnetic field, and is moving in a direction perpendicular to the field, then each charge q in the wire experiences a magnetic force of magnitude F = qvB. The negatively charged electrons will accelerate in response to this force.

## Why does the coil rotate anticlockwise?

This means that the current in the left hand part of the coil still causes a downward force, and current in the right hand part of the coil still causes an upward force. This means that the motor effect forces continue to cause anti-clockwise rotation of the coil.

## When magnetic field is perpendicular to the plane of the loop?

At time t = 0, plane of the loop is perpendicular to the magnetic field. Induced emf produced in the loop is maximum when plane of loop is parallel to magnetic field. Reason When plane of loop is parallel to magnetic field, then magnetic flux passing through the loop is zero.

## What is the magnetic flux when the loop is perpendicular?

When the field is constant and the loop is perpendicular to the field, we define the magnetic flux as the product of the magnetic field B times the area A: Φ = B × A . Flux (magnetic): It is a measure of the magnetic field that passes through a surface.

## What is the difference between coil and plane of coil?

The “plane of the coil” usually just means the surface the coil is lying in or on. For example, if a coil were lying on a table, the tabletop would be the plane of the coil. If it were hung against a wall, the wall would be the plane of the coil.

## When the plane of the coil is perpendicular in a AC generator?

In an A.C. generator, when the plane of the armature is perpendicular to the magnetic field. both the flux linked and induced emf in the coil are zero. the flux linked with it is zero, while induced emf is maximum.

## What is the angle of inclination of the thread to the imaginary perpendicular line called?

10. PITCH: Distance from one point of the thread to another thread. It is measured parallel to the axis of thread. 11. HELEX ANGLE: The angle of Inclination of thread to the imaginary perpendicular line.

## What is meant by plane of coil?

The plane of the coil is parallel to the magnetic lines of force. It is said that a current is passed through this coil in the magnetic field. We know that due to the current in the coil, the magnetic field will exert a force on the coil and due to this force the coil will start to oscillate.

## Is electric field always perpendicular to plane?

Since electric field exerts a force on the charges, now we have a force on the charges along the surface. This force isn’t balanced, so it will then move charges around i.e, there would be surface currents. So, to avoid that electric field must emanate perpendicular to surfaces.

## What is the magnetic field of a moving coil?

The nature of the magnetic field in a moving coil galvanometer is Radial magnetic field. A radial magnetic field is one in which field lines are directed from the center outwards, similar to the spokes in a bicycle wheel.

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

When current flows though a coil , its one of face acts as a north pole and the other face acts as a south pole. When this coil is placed between opposite magnetic poles, due to interacting magnetic fields, a turning effect is produced in the coil and it rotates such that its north pole face the south pole.

## What will be the direction of force when coil is placed perpendicularly to the magnetic field in a DC motor?

Now when the coil has turned such that the coil’s plane is perpendicular to magnetic field plane, the long wires do experience a downward and upward force but they cancel out.

## What effect does magnetic field have on coil?

When current flows through a conductor or a coil, a magnetic field is set up. This magnetic field increases as the current increases and decreases as the current decreases. The magnetic field’s (or magnetic flux’s) direction created around the conductor or a coil (solenoid) can be found using the right-hand rule.

## What happens when two magnets are placed perpendicular to each other?

The two magnetic fields will repel and subsequently “cancel” at the points of closest proximity of similar polarity. By “cancel” I mean that the net force from magnetism of a mathematical point at the boundary of the two repelling fields will be zero in an ideal, hypothetical environment.
