A square loop of side 
enters a magnetic field with a constant speed of 
as shown. The front edge enters the field at . Which of the following graph will correctly depicts the induced emf in the loop? [Take clockwise direction positive]
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
Magnetic field,
Speed,
Length,
Induced emf,
As, the loop enters in the field, the induced emf is negative, as it moves completely in the magnetic field the emf is zero and when it leaves the magnetic field, the emf is positive
