Question

The magnetic field strength at a point due to a current carrying circular wire depends on _________.

• A. The magnitude of the current flowing through the wire.
• B. The distance of the point from the wire.
• C. The number of loops the wire has.
• D. All the above

Answer 1

The correct option is D

All the above

The magnetic field strength due to a current carrying conductor depends on the magnitude of current flowing, the distance of the point from the conductor, the number of loops the conducting wire has and also the direction of current in the wire.
