Задача 30920.

In a uniform magnetic field, the induction of which is 1 T in a plane perpendicular to the induction lines, there is a conductor in the form of a semiring with a length of L = 20 cm through which a current of 1 A flows. Find the force acting on the conductor from the magnetic field. The field is directed perpendicular to the plane of the conductor.

A detailed solution with a brief record of the conditions, formulas and laws used in the decision, withdrawal of the calculated formula and the answer.
If there are questions about the solution, write. I try to help.
