4. B = 0.1 T A square loop of wire with side length 25 cm carries a 2A current and is located in a uniform magnetic field. The left side of the loop attached to a fixed axis (dashed line). When the plane of the loop is parallel to the magnetic field in the position shown, what is the magnitude of the torque exerted on the loop about the axis? (Use GUESS method.) Answer r=0.0125 Nm
