Task id16561

In a vertical magnetic field, a straight conductor of length l = 8 m moves at an angle a = 30° to the horizon with a speed v = 200 m/s (Fig.). The angle between the longitudinal axis of the conductor and the horizontal component of its speed is b = 60°. In this case, an emf is excited in the conductor. induction Eind = 2 kV. Find the magnetic field induction, as well as the work done by the magnetic field forces in one minute, if the resistance of the moving conductor is R = 10 Ohms.
