Question

The magnetic field lines due to a conductor are shown below. Then which of the following statements is true?

• A. No current flows in AB
• B. Current flows from B to A
• C. Current flows from A to B
• D. The current flowing through AB is alternating in nature.

Answer 1

The correct option is C Current flows from A to B

According to right hand thumb rule, when we curl our fingers in the direction of magnetic field around a current carrying wire, our thumb points in the direction of the current. Hence, the current flows from A to B.
