APFIVE Magnetic Flux in a Non-Uniform Field
A square loop with side length L moves at constant velocity v along the x-axis. Its plane remains perpendicular to a magnetic field that varies with position as $$B(x) = B_0 x^2$$, with x being the distance from the origin. How does the magnetic flux through the loop change as it moves?
A
It increases cubically with time
B
It increases quadratically with time
C
It increases linearly with time
D
It remains constant
