Why does magnetic force act from a distance?

The magnetic force can act from a distance because of the magnetic field that is created around it. It can be defined as imaginary lines around the magnet upto which it has magnetic force.

If a piece of iron is put into the magnetic field but has a slight distance from the magnet, it will be pulled towards the magnet because it is in its magnetic field.

The south pole and the north poles of the magnet has effect on each other. Same poles repeal each other and opposite poles attract each other resulting in forming a field of attraction or repulsion.

The imaginary lines created are known as magnetic field which is responsible for the magnetic force from a distance.

newton's first law of motion

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
