Two coils of wire A and B are placed mutaully perpendicular as shown in the figure. When current is changed in any one coil, will the current be induced in another coil?

Two circular conductors are perpendicular to each other as shown in figure. If the current is changed in conductor B, will a current be induced in the conductor A,

Two circular conductors are perpendicular to each other as shown in the figure.If current in any one is changed, will there be induced current in the other ?

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

When current in a coil changes with time, how is the back e.m.f. induced in the coil related to it?

A magnet is moved towards a coil. What is the source of electric current induced in the coil?

A small retangular coil ABCD contains 140 turns of wire. The sides AB and BC of the coil are of length 4.5 and 2.8 cm respectively, as shown in the figure The coil is held between the poles of a large magnet so that the coil can rotate about an axis thorugh its centre. The magnet produces a uniform magnetic field of flux density B between its poles. When the current in the coil is 170 mA, the maximum torque produced in the coil is 2.1 xx 10^-3 N m . The current in the coil in (a) is switched off and the coil s positioned as shown in the figure. The coil is then turned thorugh an angle of 90^@ in a time of 0.14 s. Calculate the average e.m.f. induced in the coil.

A rectangular ABCD is roated anticlockwise with a uniform angular velocity about the axis shown in the figure. The axis of rotation of the coil as well as the magnetric field B are horizontal. The induced e.m.f. in the coil would be maximum, when the plane of the coil

The circuit arrangement given in the figure shows that when an ac. passes through the coil A, the current starts flowing in the coil B. Mention two factors on which the current produced in the coil B depends.
