The North-pole of a long horizontal bar magnet is being brought closer to a vertical conducting plane along the perpendicular direction. The direction of the induced current in the conducting plane will be:
1 Horizontal
2 Vertical
3 Clockwise
4 Anti-clockwise
Explanation:
The induced emf will oppose to the motion of the magnet. Applying the right hand rule, the direction of induced current will be anticlockwise.

Statement A : Lenz's law violates the principle of conservation of energy. Statement B : Induced emf always supports the change in magnetic flux responsible for its production.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
Lenz's law states that the direction of induced emf always oppose the change that cause it. It is a direct consequence of the law of conservation of energy. So, option (4) is correct.

Consider the situation shown in the figure. If the current \(I\) in the long straight conducting wire \(XY\) is increased at a steady rate then the induced e.m.f. in loops \(A\) and \(B\) will be
1 Clockwise in \(A\), anti clockwise in \(B\)
2 Anti clockwise in \(A\), clockwise in \(B\)
3 Clockwise in both \(A\) and \(B\)
4 Anti clockwise in both \(A\) and \(B\)

A magnet \(NS\) is suspended from a spring and while it oscillates, the magnet moves in and out of the coil \(C\). The coil is connected to a galvanometer \(G\). Then as the magnet oscillates:
1 \(G\) shows deflection to the left and right with constant amplitude
2 \(G\) shows deflection on one side
3 \(G\) shows no deflection
4 \(G\) shows deflection to the left and right but the amplitude steadily decreases.
Explanation:
Due to damping the amplitude of the magnet decreases. The current direction changes periodically and hence galvanometer deflects.
