Question

Which expression relates magnetic induction or flux density to magnetic intensity and magnetisation?

Options

• \[B=\mu_0(H+M)\]

• \[B=\frac{H+M}{\mu_0}\]

• \[B=\mu_0(H-M)\]

• \[B=H+\mu_0M\]

Answer 1

Magnetic induction or flux density is given by \[B=\mu_0(H+M)\]. Both magnetic intensity and magnetisation appear inside the parentheses.
