Question

Suppose we have a solenoid with two ends A and B. If current at face A is clockwise while at B is anticlockwise. So, A and B act as:-

• A. A as north pole and B as south pole
• B. B as north pole and A as south pole
• C. Both A and B as north pole
• D. Both A and B as south pole

Answer 1

The correct option is A

A as north pole and B as south pole

Current at face A is flowing in a clockwise direction so it acts as "south pole" while at B current is flowing in an anticlockwise direction so it acts as "north pole".
