Effect of Frequency
a.From equation for given H p and μ
P v α √f
b.From equation the depth of penetration for a given material
δ α 1/ √f
c.From equation hysteresis losses
Wh α f
d.For a greater thermal conductivity of the material the frequency requirement will be high whereas for a greater resistivity of the material requirement of frequency will be less.
e.The flux density in ferromagnetic material will be higher than that in nine magnetic material hence in ferromagnetic material less frequency is required to produce same amount of heat.
