According to the wire length l = 60 cm, in a uniform magnetic field with induction B = 1.2 T, and located in a plane perpendicular to the direction of the field, the current I flows from the power source to the voltage U = 7 V. For wire acts the electromagnetic force F, Move it a speed V = 8 m / s. Resistance wire connecting wires R = 0,5 Ohm. Determine the value of the current I0 at a fixed wire, back-EMF induced in the wire, and the current I when it is moved.
Detailed solution shorthand terms, formulas and laws used in the decision, the withdrawal of the calculation formula and the response.
If you have any questions to address, please. I´ll try to help.
