E=Blv=2*.1*5=1volt
Now the sign (+-) will depend on the right hand rule, and I have no idea what the figure looks like.
A metal rod is moving in uniform magnetic field of 2T with a velocity perpendicular to the direction of the field as shown on the diagram. If the speed of the rod is 5m/s and the distance between points A and B is 0.1 meters what is the potential difference (voltage) between point A and point B?
(-1V)
ok so i know the equation i will be using is motional emf equaiton but i'm very confused. the answer is -1 V but how?
