The magnetic field B and the magnetic intensity H in a material are found to be `1*6T` and `1000Am^-1`, respectively. Calculate the relative permeability `mu_r` and susceptibility of the material. What is the nature of the material?

Text Solution

Verified by Experts

Here, `B=1*6T`, `H=1000Am^-1`
`mu_r=B/H=(1*6)/(1000)=0*0016`
From `1+chi_m=mu_r`
`chi_m=mu_r-1=0*0016-1=-0*9984`
As susceptibility is negative and less than one, the material must be diamagnetic in nature.
