Same as problem `4` except the coil `A` is made to rotate about a vertical axis in the plane of the coil (Figure). No currents flows in `B` if `A` is at rest. The current in coil `A`, when the current in `B` (at `t = 0`) is counterclockwise and the coil `A` is as shown at this instant, `t = 0`, is

A

constant current clockwise.

B

varying current clockwise.

C

varying current clockwise.

D

constant current counterclockwise.

When current is allowed to flow through a coil of wire, the coil

A circular of radius 0.157 m has turns. It is placed such that its axis is in magnetic meridian. A dip needle is supported at the centre of the coil with its axis of rotation horizontal, and in the plane of the coil. The angle of dip is 30^(@) when a current flows through the coil. The angle of dip becomes 60^(@) on reversing the current. Find the current in the coil assuming that the magnetic field due to the coil is smaller than the horizontal component of earth's magnetic field, H =3xx10^(-5) T .

Observe the following figure. If the current in the coil A is changed, will some current be induced in the coil B? Explain.

If plane of coil and uniform magnetic field B(4T0 is same then torque on the current carrying coil is

Two circular coils A and B are placed close to each other. If the current in the coil A is changed, will some current be induced in the coil B? Give reason.

A constant current of 3.0 A flows counterclockwise in the circular coil in the following figure. What is the direction of the induced current in the coil on the right?

There are two coils A and B as shown in Figure. A current starts flowing in B as shown, when A is moved towards B and stops when A stops moving. The current in A is counterclockwise. B is kept stationary when A moves. We can infer that
