Question

A conductor ABOCD moves along its bisector with a velocity 1 m/s through a perpendicular magnetic field of 1 Wb/m2, as shown in figure. If all the four sides are 1 m length each, then the induced emf between A and D (in Volt) is approximately


(upto two decimals)

Solution


Induced emf between A and D
VAVD=V×B×L ...(1)
From triangle BOC
Lsin90=1sin45
L=2 m
From equation (1),
VAVD=1×1×2=1.41 Volt
