Question

Magnetic lines of force are

• A. continuous closed curves
• B. never intersect each other
• C. more concentrated at poles
• D. all of the above

Answer 1

The correct option is D

all of the above

Explanation for correct option:

Option (D):

1. Magnetic lines of force are the lines that depict the magnetic force that exists in the surrounding of the magnet.
2. Magnetic field lines outside of the magnet emerge from the north pole and merge at the south pole.
3. The direction of field lines inside the magnet is from the south pole to the north pole.
4. Thus, magnetic lines of force form continuous closed curves.
5. Magnetic lines of force never intersect each other.
6. Magnetic lines of force are more concentrated at poles.

Thus, all the above options are true for magnetic lines of force.

Hence, option D is the correct option.
