An equilateral triangular loop ADC of uniform specific resistivity having some resistance is pulled with a constant velocity v out of a uniform magnetic field directed into the paper. At time t = 0, side DC of the loop is at the edge of the magnetic field. The induced current (I) versus time (t) graph will be as:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
Let 
be the side of the triangle and 
the length 
.
Thus, 
graph is a straight line with negative slope and positive intercept.
