The figure shows a conducting loop being pulled out of a magnetic field with speed v. Which of the four plots shown in the figure may represent the power delivered by the pulling agent as a function of the speed v?
Formula used: The emf developed across the ends of the loop is given by
Where v is the speed
B is the magnetic field
L is the length
The power delivered to the loop is
Where P is the Power delivered to the loop
R is the resistance
is the emf induced
From the above equation, P is proportional to v2. Curve b showing this relation.
