Answer 1

Answer:

(iv) Deflection in the needle becomes opposite when the direction of the current reverses.

Explanation:

In the first circuit the direction of the current was clockwise so compass needle pointed in the north east direction. Whereas in the second circuit the direction of the current is anticlockwise (reversed) so now compass needle will point in the north west direction.

In short compass needle points in the direction of the current.
