Question

In electric fields, D= ε E. The correct expression which is analogous in magnetic fields will be

(a) H = μ B

(b) B = μ H

(c) A = μ B

(d) H = μ A

This question was addressed to me in class test.

I would like to ask this question from Real Time Applications topic in chapter Electrostatic Fields of Electromagnetic Theory

Answer 1

Right option is (b) B = μ H

For explanation: In electric fields, the flux density is a product of permittivity and field intensity. Similarly, for magnetic fields, the magnetic flux density is the product of permeability and magnetic field intensity, given by B= μ H.
