Suppose you double the magnetic field in a given region and quadruple the area through which this magnetic field exists. The effect on the flux through this area would be to
A) leave it unchanged.
B) double it.
C) quadruple it.
D) increase it by a factor of 6.
E) increase it by a factor of 8.

Question

Quizplus · Accepted Answer

Magnetic flux is given by the product of the magnetic field and the area it penetrates. Doubling the magnetic field and quadrupling the area results in an 8-fold increase in the magnetic flux.
