Question

An electric current flows in a horizontal wire from East to West. What will be the direction of magnetic field due to current at a point (i) North of wire; (ii) above the wire

Answer 1

Answer:

See below.

Explanation:

The electric current flowing through a horizontal wire flows from east to west.

See the diagram attached.

Using the Right Hand Thumb Rule, the direction of the magnetic field at a point,

a) North of the wire -> inward ( going into the plane of the paper )

b) Above the wire -> inward ( going into the plane of the paper )

That gives us the answer.
