An electron is passing near a ring and approaches to ring, then the direction of induced current in the ring is:
Important Questions on Electromagnetic Induction
The north pole of a magnet is brought near a metallic ring as shown in fig. The direction of induced current in the ring will be-
Consider the situation shown in fig. If the switch is closed and after some time it is opened again, the closed loop will show
A small, conducting circular loop is placed inside a long solenoid carrying a current. The plane of the loop contains the axis of the solenoid. If the current in the solenoid is varied, the current induced in the loop is
Figure shows a horizontal solenoid connected to a battery and a switch. A copper ring is placed on a frictionless track, the axis of the ring being along the axis of the solenoid. As the switch is closed, the ring will
Two circular coils A and B are facing each other as shown in figure. The current i through A can be altered
