is moved When the arm MN of length 20cm. towards left with a velocity of 10m * s ^ - 1 , Calculate the emf Induced in the arm.
Given the resistance off the arm be 52.
Cassuming that other arms are of negligible. resistance) find the value of current in the arm.
B = 0.5T
l = 20cm = 0.2m
v = 10m * s ^ - 1
T = e/R
|e| =
R = 5Omega

|e|= |- B| * v |
= \{- 0.5 * 0.2 * 10\}
= 2 5 -0.2N = (- 1/10 * 10) = 1V
