Question

For an isotropic medium B, µ, H and M, are related as (where B, µ₀, H and M_z have their usual meaning in the context of magnetic material) ____________.

Options

• `("B" - "M"_z) = mu_0"H"`

• `"M" = mu_0 ("H" + "M"_z)`

• `"H" = mu_0 ("H" + "M"_z)`

• `"B" = mu_0 ("H" + "M"_z)`

Answer 1

For an isotropic medium B, µ, H and M, are related as (where B, µ₀, H and M_z have their usual meaning in the context of magnetic material) `"B" = mu_0 ("H" + "M"_z)`.

Explanation:

Net magnetic induction B

`= "B"_0 + "B"_m`

`= mu_0"H" + mu_0 "M"_z`
