As the distance from a magnet increases, what happens to the magnetic force?

Explanation :

The magnetic force is given by :

or

............(1)

Where

q is the charge

v is the velocity with which it is moving

B is the magnetic field

is the angle between the velocity and the magnetic field.

We know that the magnetic field is inversely proportional to the distance.

So, the force will also inversely proportional to the distance.

Hence, as the distance from a magnet increases, the magnetic force decrease.

b. the carbon cycle ensures living things have a source of hydrogen
