Question

Study the diagram alongside carefully and answer the following question:

The direction of the magnetic lines of force around A and B will be:

पर्याय

• clockwise around both A and B.

• anticlockwise around both A and B.

• clockwise around A and anticlockwise around B

• anticlockwise around A and clockwise around B.

Answer 1

Anticlockwise around A and clockwise around B.

Explanation:

Using the right-hand thumb rule, at A the current is directed upwards, so the magnetic lines around A are anticlockwise. At B, the current is directed downwards, so the magnetic lines around B are clockwise.
