Question

On which variable does magnetic flux depend?A) the magnetic fieldB)the orientation of the field with respect to the region through which it passesC)the area of a region through which magnetic field passesD)all of theseE)none of these

Answer 1

Answer:

D) All of these

Explanation:

The magnetic flux through a coil of wire is given by:

$\Phi = BA cos \theta$

where

B is the intensity of the magnetic field

A is the area enclosed by the coil

$\theta$ is the angle between the direction of B and the normal to the area of the coil

Therefore, we see that the magnetic flux depends on all these quantities:

A) the magnetic field

B)the orientation of the field with respect to the region through which it passes

C)the area of a region through which magnetic field passes

So, the correct answer is

D) All of these
