Question

_________is the pattern of magnetic field around a straight current carrying conductor.

• A. Parallel lines
• B. Concentric helix
• C. Concentric circles
• D. Concentric spiral

Answer 1

The correct option is C

Concentric circles

Magnetic field lines form closed loops. These lines give the direction of magnetic field around a conductor. So the pattern of field lines around the current carrying conductor is similar to concentric circles.
