Statement-1: A vertical iron rod has ciol of wire wound over it at the bottom end. An alternating current flows in the coil. The rod goes through a conduction ring as shwon in the figure. The ring can float at a certain height above the coil.
Statement -2: In the above situation a current is inuced in the ring which interacts with the horizontal components of the magnetc field to produce an aberage force in the upward direction.

Options

A. Statement-1 is true, statement-2 is true, Statement-2 is a correct explanation for Statement-1
B. Statement-1 is true, statement-2 is true, Statement-2 is NOT a correct explanation for Statement-1
C. Statement-1 is true, statement-2 is False
D. Statement-1 is false, Statement-2 is True.

Answer

A

Explanation

As shown in the figure the horizontal components of the magnetic field interacts with the induced current produced in the conducting ring which produce an average force in the upward direction. (Fleming's left hand rule).
