(c) B=μr μ0 H (d) All of the above

Answer 1

Answer:

don't know sorry

Answer 2

Relation between B, H and M

Explanation:

• Now, B is generally the flux density, H = magnetic field intensity and M = magnetisation
• The relation between B and H can be represented as a ratio; the B/H ratio is always constant and equal to the permeability of the material

1. B = μH = μr μ0 H  ( in medium )
2. B = μ0 H ( in air )

here μ0 = absolute permeability

and μr = relative permeability ( the ability of a substance to conduct magnetic field lines of force as compared to the air)

• Also, the relation between B, H and M is represented as B = μ0(M+H)
• Thus, the relation between them is best represented as (d) all of the above.
