MCQ
Magnetic field intensity is defined as
  • A
    Magnetic moment per unit volume
  • ✓
    Magnetic induction force acting on a unit magnetic pole
  • C
    Number of lines of force crossing per unit area
  • D
    Number of lines of force crossing per unit volume
✓

Answer

Correct option: B.
Magnetic induction force acting on a unit magnetic pole
Number of lines of force passing through per unit area normally is intensity of magnetic field, hence option (c) is incorrect. The correct option is (b).
