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

Text Solution

Verified by Experts

Intensity of magnetisation `M= 10^(6) A//m`
Length `l=10 cm = 10^(-1)` m
`I_(M) =` magnetisation current
We know that,
`M= (I_(M))/( l)`
`therefore I_(M) = Ml`
`= (10^6) (10^(-1) ) `
`=10^(5) A`
