plane of eddy currents make an angle with the plane of magnetic lines of force equal to

How eddy current are produced in the magnetic breaking of trains?

The figure below shows the north and south poles of permanent magnet in which n turn coil of area of cross-section A is resting, such that for a current I passed through the coil, the plane of the coil makes an angle with respect to the direction of magnetic field B . If the plane of the magnetic field and the coil are horizontal and vertical respectively, the torque on the coil will be

Assertion : If a varying current is flowing through a machine of iron, eddy currents are produced. Reason : change in the magnetic flux thro' an area causes eddy currents.

A coil is suspended in a uniform magnetic field, with the plane of the coil parallel to the magnetic lines of force. When a current is passed through the coil it starts oscillating, It is very difficult to stop. But if an aluminium plate is placed near to the coil, it stops. This is due to :

Obtain an expression for the torque acting on a current carrying rectangular coil placed in a uniform magnetic field when the plane of the coils is parallel to the magnetic lines of force.

On any plane perpendicular to a long straight current carrying conductor, the magnetic lines of force are circular. Discuss whether these circular lines of force are equidistant.
