Question

Magnetic lines of force inside a bar magnet

• A. Are from north pole to south pole of the magnet
• B. Do not exist
• C. Depend upon the area of cross section of the bar magnet
• D. Are from south pole to north pole of the magnet

Answer 1

The correct option is D Are from south pole to north pole of the magnet

Answer is D.
Magnetic lines of force, do not actually exist but are imaginary lines used to illustrate and describe the pattern of the magnetic field. The magnetic lines of force are assumed to emanate from the north pole of a magnet, pass through surrounding space, and enter the south pole. The lines of force then travel inside the magnet from the south pole to the north pole, thus completing a closed loop.
