A circular loop of area `1 cm^(2)` carrying a current of `10A` is placed in a magnetic field of `2That(i)`. The loop is in `xy` plane with current in clockwise direction . Fing the torque on the loop

Text Solution

Verified by Experts

`vec(tau)=vec(M)xxvec(B) =(nivec(A) xx vec(B))`
`=[10xx10^(-4)(-hat(k))]xx(2hat(j))=2xx10^(-3)Nm(hat(i))`
