What is the net force on the rectangular coil
A rectangular coil of wire carrying a current is suspended in a uniform magnetic field. The plane of the coil is making an angle of 30^(@) with the direction of the field and the torque experienced by it is tau_(1) and when the plane of the coil is making an angle of 60^(@) with the direction of the field the torque experienced by it is tau_(2) . Then the ratio tau_(1):tau_(2) is
A torque of 2.5 Nm acts on a current carrying rectangular coil of area 0.2 m^(2) , suspended vertically in a uniform magnetic field. What is the torque, if the rectangular coil is replaced by a plane circular coil of the same area? [all other quantities are unaltered]
