The maxiumum value of the permeability of metal (77% Ni, 16% Fe, 5% Cu, 2% Cr) is `0.128 Tm A^(-1)`. Find the maxiumum relative permeability and susceptibility.

Text Solution

Verified by Experts

Relative permeability is
`mu_r = mu/mu_0 = (0.126 Tm A^(-1))/(4pi xx 10^(-7) Tm A^(-1)`
`1.00 xx 10^5`.
Susceptibility `chi = mu_r - 1 = 1.00 xx 10^5`.
