Question

The magnetic lines of force due to a bar magnet are :

• A. Curved lines
• B. Curved closed loops
• C. Concentric circles
• D. Parallel and straight

Answer 1

The correct option is B Curved closed loops

It is the property of the force of the magnetic field line that lines of force are closed curves. Which starts in the air from the North pole and ends at the South pole and then returns to the North pole through the interior of the magnet.

Hence, the magnetic lines of force due to a bar magnet are curved close loops lines.
