Magnetic field strength decreases as you get farther from the poles of the magnet.
<h3>Explanation</h3>
There are three ways to change the magnetic flux across a loop: Change the strength of the magnetic field across the surface (raise, reduce).
It doesn’t matter whether you move the coil while keeping the magnet fixed or the other way around if you want to change the surface area of the loop (raise by expanding the loop, decrease by reducing the loop).
The way they move in respect to one another determines how the magnetic flux across the coil changes. The direction in which the galvanometer needle deflects depends on which side of the coil confronts the magnet when you move it. The coil ends are labelled to show which goes to the red wire and which goes to the black wire.

Answer:
When the electric force between two charged objects change, the distance between the objects increases in Iicreasing the separation distance between objects and decreases the force of attraction or repulsion between objects.
