Задача 30464.

A conductor 20 cm long with a mass m = 2 g, suspended horizontally on thin wires, is in a uniform magnetic field, the lines of force of which are directed vertically upward. When a current of 0.3 A passed through the conductor, it deviated so that the wires formed an angle of 11° with the vertical. Find the magnetic field induction.
