Question
In the diagram, rectangular loop X is just entering a region with a uniform magnetic field directed out of the page, and loop Y is just leaving. Both loops are identical, with a length to width ratio L/W equal to 4, but they are oriented differently as shown. The arrows indicate the direction of motion. What is the direction of induced current in each loop? The induced emf has magnitude .20 V in Loop X and .10 V in Loop Y. If Loop X moves with velocity v, what must be the velocity of Loop Y? Give your answer in terms of v.
Explanation / Answer
n case of X....direction of induced current is clockwise......But in Y ......direction is anticlockwise......Its because in X its downward on right side but on Y its downward on left side of the loop which is inside the magnetic fied......
Emf induced is equal to BLV........therefore.....for X...E= Bwv=.20.....for Y..E= BLv'=.10....dividing both.....v'=wv/2L= (W/L)*.5 * v = .25*.50*v = 0.125 v......
