Coulomb's Law
When Using Coulomb's Law, you need to have two or more forces of magnetization. This is an equation when you want to calculate the force between the two or more objects with this force. Make sure you also have the distance between the two objects unless you're solving for it.
Equation for Coulomb's Law:
Key-
q1- 1st charge unit
q2- 2nd charge unit
r- Meters/distance between objects
k- 9x10^9
