PROBLEM 2.62
Perpendicular to the lines of induction of a homogeneous magnetic field by induction of 1 mT in two parallel conductors, a 20 cm long bridge moves without friction. When the circuit containing this bridge is closed, a current of 0.01 A flows in it. Determine the speed of the rider´s movement. The resistance of the circuit is 0.1 ohms.
