Question
The correct pattern of magnetic field lines of the field produced by a current carrying circular loop is:
Options
Solution
Explanation:
Magnetic field lines enter from the south pole and exit from the north pole. A circular coil that conducts current has curved lines, a straight line running through the centre, and concentric circles at the coil's two opposite ends.
