Задача 30195.

In a uniform magnetic field with induction B = 0.3 mT there is a flat square circuit with side a = 10 cm, in which a constant current strength I = 6 A is maintained. The plane of the contour is perpendicular to the lines of magnetic induction. Determine the work required to move the circuit from the magnetic field to a region of space where there is no field.
