Question

Why is magnetic induction or magnetic flux density dependent on the medium?

Answer 1

The magnetic flux generated in a medium is the response of the medium to the applied field. The total flux generated thus is

B_total= B_applied + B_medium

Now the relative permeability of the medium determines the way it responds to the applied field. You can find a detailed explanation in ‘Advanced Electromagnetics’ by Balanis in chapter 2 or 3 I guess, where the explanation for constitutive parameters is given.

$\mathfrak{\blue{Q.}}$Why is magnetic induction or magnetic flux density dependent on the medium?

$\mathfrak{\blue{Ans.}}$magnetic flux depends on magnetic field and the magnetic field depends on permeability of the medium. So, by transitivity :P magnetic flux depends on permeability of a medium and permeability is the property of the medium.
