Question

A 5 cm bar is moving with a constant velocity v = 5сm/s a rail track in a region of constant magnetic field B = 5 mT2, as shown in

the Figure. a) Evalute the induced potential difference Vind- b) Where is the induced potential difference Vind located? c) What is the direction of the induced potential difference Vind? (high-to-low values direction). d) A circuit is added, as shown in the 2nd Figure. How fast would the bar have to move instead to supply a 5 A current to a 5 N load?
