A) The compass needle points towards the right.
B) The compass needle points towards the left.
C) The compass needle points towards upward.
D) The compass needle points toward downward.
Correct Answer: D
Solution :
A current-carrying wire will produce circular magnetic field around the wire. The direction of the magnetic field follows the right hand grip rule. When the current flows from A to B, the magnetic field around the wire is shown in the figure. Since the compass is placed in front of the wire, it will follow the direction of the magnetic field and turn to the right.You need to login to perform this action.
