22. The power supply to the electromotive force ε = 0,5 V and negligible internal impedance are attached two metal rods arranged horizontally and parallel to each other. The distance L between the bars is 20 cm. Bars are located in a uniform magnetic field directed vertically. Magnetic induction B = 1.5T. According to the terminals by the forces of the field with speed slides υ = 1 m / s straight wire AB resistance R = 0,02 Ohm. The resistance of the rods is negligible. Define:
1. EMF induction;
2. force F, acting on the wire from the field;
3. The strength of the current in the circuit;
4. P1 power expended on the movement of the wire;
5. P2 power expended in heating the wire;
6. The power P3 to give the circuit a current source.
