Vaughn Wilkinson · Answer 1

option (a)

Explanation:

The direction of current is upwards and magnetic force is towards right.

By using the Fleming's left hand rule, the thumb denotes the direction of force, fore finger denotes the direction of magnetic field and middle finger denotes the direction of current.

So, the direction of magnetic field is perpendicularly inwards to the plane of screen.

Thus, option (a) is correct.
