Please answer the question .....​

Answer 1

Step-by-step explanation:

Here, n=500 turns/m

I=1A,μ

r

=500

Magnetic intensity, H=nI=500m

−1

×1A=500Am

−1

As μ

r

=1+χ

where χ is the magnetic susceptibility of the material

or χ=(μ

r

−1)

Magnetisation, M=χH

=(μ

r

−1)H=(500−1)×500Am

−1

=499×500Am

−1

=2.495×10

5

Am

−1

=2.5×10
