The plane of a rectangular loop of wire with sides 0.05 m and 0.08 m is parallel to a uniform magnetic field of induction . A current of 10.0 ampere flow through the loop. If the side of length 0.08 m is normal and the side of length 0.05 m is parallel to the lines of induction, then the torque acting on the loop is
Torque acting on a current carrying coil of area A placed in a magnetic field of
induction B is given by
Where =current in the coil, =angle which the normal to the plane of the coil makes with
the lines of induction B.
Here,
