Question

An iron rod is placed in magnetising field of 1000 A/m calculate the magnetic permeability of an iron rod ( magnetic susceptibility 59.9 magnetic permeability of vaccum 4 JI × 10^-7​

Answer 1

Answer:2.50×10-4

3.80×10-4

7.54×10-4

7.20×10-4

Answer :

C

Solution :

Here, A=0.1m2,H=100

A

m

 

andχm=599

μ0=4Pi×10-7T

m

A

 

μ=μ0(1+χm)

=4Pi×10-7(1+599)
