What is velocity-consider a set of conducting metal tracks

Reference no: EM13681382

Consider a set of conducting metal tracks (two parallel beams by a flat top surface) 0.3 m apart. Across the tracks, perpendicular to them is a conducting rod of mass 0.65 kg. There is a uniform magnetic field of 0.80 T [Tesla, the SI unit of magnetic field strength, 1T = 1 N / (A m),] pointing down. A circuit consisting of a 47 Ohm resistor and a 15 V power supply is placed across the rails. After some time in motion, the velocity is constant. What is that velocity?

Hint: The velocity is constant when the induced electromotive force is equal and opposite to the voltage applied to the rails. Please show work.
