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 six.
E)increase it by a factor of eight.

Question

Quizplus · Accepted Answer

Magnetic flux is given by the product of the magnetic field strength and the area through which the field lines pass. If the magnetic field is doubled and the area is quadrupled, the flux would increase by a factor of 2 (from the magnetic field) times 4 (from the area), resulting in an overall increase by a factor of 8.
