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

Answer» Solution :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` |
