A circular coil of radius 2.0 cm has 500 turns in it and carries a current of 1.0 A . Its axis makes an angel of `30^@` with the uniform magnetic field of 0f magnitude 0.40 T that exists in the space. Find the torque acting on the total.

Explanation

`N = 500, r = 0.02 m,`
`theta =n 30^@ , l = L,A , B = 0.4 T, `
`mu = nia B sin 30^@`
`= 500 xx 1 xx 3.14 xx 0.02 xx 0.02 xx 0.4 xx (1)/(2) `
` = 12.56 xx 10^(-2) `
` = 0.1256 = 0.13 N.m `
