(a) A circular coll of 30 turns and radius 8.0 cm carrying a currentof 6.0 A is suspended vertically in a uniform horizontal magneticfleld of magnitude 1.0 T. The field lines make an angle of 60^° with the normal of the coil.calculate the magnitude of the counter torque that must be applied to prevent the coil from turnin |
