classical mechanics,relativity and electromagnetism
The three main branches of physics are classical physics (which includes mechanics, thermodynamics, and electromagnetism), quantum physics (which deals with the behavior of particles on the atomic and subatomic scales), and relativity (which encompasses general relativity and special relativity, describing the behavior of objects at high speeds or in the presence of strong gravitational fields).
That is, basically, the way ALL magnets are created - by moving electric charges. In the case of a permanent magnet, it is mainly the electrons orbiting their atoms that produce this effect. As to the "why", the Special Theory of Relativity provides an answer, but it is fairly complicated. The summary paragraph on Wikipedia (article "Magnetism") says: "As a consequence of Einstein's theory of special relativity, electricity and magnetism are fundamentally interlinked. Both magnetism lacking electricity, and electricity without magnetism, are inconsistent with special relativity, due to such effects as length contraction, time dilation, and the fact that the magnetic force is velocity-dependent. However, when both electricity and magnetism are taken into account, the resulting theory (electromagnetism) is fully consistent with special relativity. ..." The Wikipedia article "Classical electromagnetism and special relativity" provides a more detailed explanation about the relationship between electricity and magnetism, according to the Special Theory of Relativity - but the math is a bit too complicated for my liking.
Relativity is a theory that describes how objects and energy interact in the universe, while special relativity is a specific branch of relativity that deals with the behavior of objects moving at high speeds. Special relativity is a subset of the broader theory of relativity, focusing on the effects of motion on space and time. Both theories are interconnected, with special relativity providing a more detailed understanding of certain aspects of relativity.
At least special theory of relativity was published 1905
Special Relativity 1905 General Relativity completed 1915 published 1916
The GRE Physics Equation Sheet includes formulas and equations related to mechanics, electromagnetism, thermodynamics, quantum mechanics, atomic and nuclear physics, optics, and special relativity.
e is energy c is the speed of light and m is the mass of the object or lightwave. C is constant while m is computable through basic calculations or through advanced upper level electromagnetism.

Special relativity deals with the physics of objects moving at constant speeds, while general relativity includes the effects of gravity and acceleration on objects in motion.
