Question:
A constant current flows from A to B as shown in the figure. What is the direction of current in the circle?
A constant current flows from A to B as shown in the figure. What is the direction of current in the circle?
Show Hint
Unless a path is conducting and part of the circuit, no current flows through it.

- Clockwise
- Anti-clockwise
- Straight line
- None of the above
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
A current flows in a straight wire from point A to B.
According to electromagnetic theory, the electric current does not flow in the nearby circular path unless it is part of the conducting circuit.
Therefore, no actual current flows in the circle.
