Answer from: Azaleaz

The magnetic flux linked with the coil will increase because the magnitude of the magnetic field is increased.

Further Explanation:

The magnetic flux linked with a coil placed perpendicular to the direction of magnetic field is given as:

$\boxed{\phi =BA\cos\theta }$

Here, is the magnetic field, is the cross-sectional and $\theta$ is the angle between the coil and the magnetic field.

The above expression shows that the magnetic flux of a coil is directly proportional to the magnetic field lines passing through the coil because more the strength of the field more will be the number of magnetic field lines passing through the coil.

The magnetic flux induced in the coil is directly proportional to the area of the coil because due to larger area of the coil more number of magnetic field lines will pass through it and the change in position of the coil will also change the magnetic flux linked with the coil.

Thus, in the above case, if the magnetic field is increased in the region, the magnetic flux of the coil will also increase.

So, the magnetic flux linked with the coil will increase because the magnitude of the magnetic field is increased.
