4-potential

The 4-potential is a concept used in physics, particularly in the context of electromagnetism and relativity. It combines electric potential and magnetic vector potential into a single mathematical framework, allowing us to describe how electric and magnetic fields interact in space and time. By using 4-potential, physicists can simplify complex equations that govern electromagnetic fields, making it easier to analyze how charged particles move under these influences. In essence, it’s a unified way to represent the potentials that give rise to electric and magnetic forces in our universe.
