All right, why are you student? so in part a, the motional emf is basically equal to the product of magnetic field strength, the length of the conducting wire times the velocity with which it is moving.
00:16
The strength of magnetic field is given that is 0 .54 tesla.
00:21
The length of the conducting wire is 0 .32 meters.
00:25
The velocity of the conducting wire is 6 meters per second.
00:30
So from here, the emotional emf equals 1000, sorry, mario student.
00:39
So this is basically equal to 1 .368, 368 volts, or if we convert this into millimiter, that is 136 .8 milliwolds.
00:59
So in part b, my dear student, we will use the using, right -hand rule that determine the direction of electric field, the fingers curl from velocity to the magnetic field, so the thumb points towards the direction of current.
01:16
So it means that there is from b to a, hence b is at higher potential.
01:23
Why? because current is flowing from b to a...
