94. Explore a thin half-rings of radius R = 10 cm is in a uniform magnetic field with induction B = 5,0 · 10-2 Tesla. Current flows through the conductor I = 10 A. Find the force acting on the conductor, if the plane of the semiring perpendicular lines of induction and the lead wires are located outside of the field.
