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.
