Задача 30373.

A straight wire with a length of l = 0.3 m, through which a current of force I = 20 A flows, is placed in a uniform magnetic field at an angle of 30° to the induction lines. Magnetic induction B = 1.5 Tesla. What work A will be done by the forces acting on the wire from the field, moving it at a distance S = 20 cm perpendicular to the field lines?
