Question

Magnetic field intensity is defined

• A. Magnetic moment per unit volume
• B. 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 1

Answer: (B)

Magnetic induction force acting on a unit magnetic pole

Answer 2

Number of lines of force passing through per unit area normally is intensity of magnetic field; hence option (3) is incorrect. The correct option is (2).
