A square coil ABCD lying in `x-y` plane with its centre at origin. `A` long straight wire passing through origin carries a current `i=2t` in negative z-direction. The induced current in the coil is

A long straight wire along z axis carries a current I in the negative z direction. The magnetic vector vecB at a point having coordinates (x, y) in the z = 0 plane is

A long straight wire along the z-axis carries a current I in the negative z-direction. The magnetic vector field B at a point having coordinate (x,y) on the z=0 plane is:

Show a conduction loop placed near a long, straight wire carrying current i as shown. If the current increases continuously, find the direction of the induced current in the loop.

Show a conduction loop placed near a long, straight wire carrying current i as shown. If the current increases continuously, find the direction of the induced current in the loop.

When current passing through a coil increases, direction of induced emf is

The north of a bar magnet is moved towards a coil along the axis passing through the centre of the coil and perpendicular to the plane of the coil. The direction of the induced current in the coil when viewed in the direction of the motion of the magnet is
