Two identical coils $A$ and $B$ are arranged coaxially as shown in the figure and the sign convention adopted is that the direction of currents are taken as positive when they flow in the direction of arrows. Which of the following statements is correct?

An electron is passing near a ring and approaches to ring, then the direction of induced current in the ring is:

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
