Question

What happens to a magnetic field if the current carrying wire A has three times as many loops but the same current as the current carrying wire B? A. Wire A will have a lower magnetic field than wire B. B. Wire A will have a magnetic field one–half as strong as wire B. C. Wire A will have a magnetic field that's greater than wire B. D. Wire A and wire B will both have the same magnetic field.

Answer 1

Answer: C.

Wire A will have a magnetic field that's greater than wire B.

Explanation: A current carrying wire conductor produces magnetic field around the wire as the wire turns and makes a loop.

if the current carrying wire A has three times as many loops as the current carrying wire B as they both carry the same current, then, Wire A will have a magnetic field that's greater than wire B.
