Question

A thick copper conductor is held parallel to a freely pivoted magnetic needle, as shown in the diagram alongside. Answer the question given below:

If the conductor is held below the magnetic needle and parallel to it, then the direction which north pole of pivoted magnetic will point, is:

पर्याय

• east

• north-east

• west

• none of these

Answer 1

west

Explanation:

Keeping the same current direction from north to south, if the conductor is placed below the needle instead of above it, the north pole deflects towards the west. Thus, moving the wire to the other side reverses the direction of deflection.
