Задача 31623.

A circular turn made of a wire of length l = 12.56 cm is placed in a uniform magnetic field by induction B = 4 mT. The current flows through the turn J = 0.6 A. The normal to the plane of the turn is an angle a = 45 ° with the direction of the lines of magnetic induction. Determine the torque of the forces M acting on the turn.

A detailed solution with a brief description of the condition, formulas and laws used in the solution, the derivation of the formula and the answer.
If you have any questions about the solution, please write. I try to help.
