Coulomb’s Law
Coulomb’s Law is a law created by Charles-Augustin de Coulomb in 1785. This law describes the force between two objects. This is directly proportional to the charge and inversely proportional to the square of the distance. This law tells you the electric force between charged objects.
This law is used everyday in everyday object like a cord/phone charger. Similarly to magnets, electrons which have negative charges and nuclei which have positive charges, both attract each other. For example, if you rub two objects together, the object gain equal and opposite charges and because of this law, they begin to attract. This can happen with a balloon against your hair which makes your hair be attracted to the balloon's charge. This is the formula:

Charles-Augustin de Coulomb
Charles-Augustin de Coulomb (1736–1806) was a French physicist, engineer, and military officer whose work laid important principles for electricity, magnetism, and mechanics. He discovered the law when he was around 48 years old. At this time he was stationed in Paris working as a military engineer in the French army’s Corps du Génie. During this time, he also invented torsion balance which allowed him to measure tiny amounts of imbalances. This led to the creation of Coulomb’s Law. He also established the inverse square law in 1785 as well but expanded them in 1787. Because of these accomplishments, the coulomb is named in his honor.
Just to be clear, electrostatics is NOT magnetism.
