Magnetic and nonmagnetic medium on wave propagation

[johndoe]

What is the difference of a magnetic and nonmagnetic medium? And how does it affect wave propagation on these mediums?

 

[m.s.j]

Material (or medium) properties determine the relations between E and D and between B and H. These relations are called the constitutive relations of a medium.

U(R,t)=f(t-R√μ€)

Above equation represents a waves traveling in the positive R direction with a veloclty
1/√μ€, where is a characteristic of the medium.
