Question

A rectangular coil of wire 50 turn each of area 6 x 10^-4 m² is freely suspended in a field of 3 x 10^-2 Wb / m². Calculate the current flowing through the coil when it deflects through 60°, when torsional constant is 3.82 x 10^-6 SI unit.

Answer 1

`I=(Ktheta)/(nAB)`

`=(3.82xx10^(-6)xx1.047)/(50xx6xx10^(-4)xx3xx10^(-2))`

`=(3.82xx1.047)/(50xx6xx3)`

`I =3.9995/900`

`=0.004443A=4.4mA`
