Answer:
The laws of magnetism have been developed and refined extensively since the experiments of Orsted, Ampere and other now-famous scientists in the early 1800s. The most fundamental law introduced during this time is the concept that the poles of a magnet each have their own distinct positive or negative charge and only attract oppositely charged poles. For example, it is nearly impossible to keep two positively charged magnetic poles from repelling each other. On the other hand, it is difficult to keep a positively charged and negatively charged magnetic pole from attempting to move toward each other.
The second law of magnetism is slightly more complex and relates directly to the electromotive force of the magnets themselves. This particular law is commonly referred to as Coulomb's Law.
Coulomb's law states that the force exerted by the pole of a magnet on an additional pole adheres to a series of strict rules, including:
The force is in direct proportion to the product of the forces of the pole.
The force exists in inverse proportion to the square of the middle distance between the poles.
The force is dependent on the specific medium in which the magnets are placed.
The mathematical formula commonly used to represent these rules is:
F = [K x M1 x M2)/d2]
In the formula, M1 and M2 represent the strengths of the poles, D is equal to the distance between the poles, and K is a mathematical representation of the permeability of the medium in which the magnets are placed.

Answer:
The most basic law of magnetism is that like poles repel one another and unlike poles attract each other; this can easily be seen by attempting to place like poles of two magnets together.
