Question

Identify the expression for magnetic induction from the following.

(a) B = μo(H+I)

(b) B = μo(H×I)

(c) B = μo(H-I)

(d) B = μo(\(\frac {H}{I}\))

This question was addressed to me in an interview.

My query is from Magnetic Properties of Materials in division Magnetism and Matter of Physics – Class 12

Answer 1

Right option is (a) B = μo(H+I)

Easy explanation: Magnetic induction (B) is defined as the number of magnetic lines of induction crossing per unit area normally through the magnetic substance, and is given by:

B = μo(H+I)

The SI unit of magnetic induction is Tesla (T).
