MCQ
Magnetic lines of force:
  • A
    Are mere directions.
  • B
    Have no physical reality.
  • C
    Can be used to indicate the direction of the magnetic field at point.
  • D
    All the above are correct.
✓

Answer

  1. All the above are correct.

Explanation:

A pictorial representation of magnetic lines of force is very useful in visualizing the strength and direction of the magnetic field. The direction of magnetic lines of force is defined to be the direction in which the north end of a compass needle points. They have no physical existence.
