A permanent magnet in the shape of a thin cylinder of length 10cm has `M=10^6 A//m`. Calculate the magnetisation current lm……

A

`10^2A`

B

`10^4A`

C

`10^5A`

D

`10^6A`

Text Solution

Verified by Experts

The correct Answer is:
C
According to formula `M=I_b/l implies I_b=Ml`
`therefore I_b= 10^6 times 10 times 10^-2=10^5 A`
