	Fundamental Forces
		One of the four fundamental forces, the electromagnetic force manifests itself through the forces between charges (Coulomb's Law) and the magnetic force, both of which are summarized in the Lorentz force law.
		The electromagnetic force is a force of infinite range which obeys the inverse square law, and is of the same form as the gravity force.
		The discovery of the W and Z particles in 1983 was hailed as a confirmation of the theories which connect the weak force to the electromagnetic force in electroweak unification.

		The forces between atoms, including the attractive forces between atoms in a solid that give rise to the rigidity of solids, are predominently electromagnetic, arising from the positive electric charge of the protons in atomic nuclei and the negative electric charge of the electrons surrounding the nuclei.
		The theory of classical electromagnetism was developed by various physicists over the course of the 19th century, culminating in the work of James Clerk Maxwell, who unified the preceding developments into a single theory and discovered the electromagnetic nature of light.
		The force that the electromagnetic field exerts on electrically charged particles is described using the Lorentz force law.

	Electromagnetic Forces
		An indication of the dominance of the magnetic force is given by a ball bearing on a table.
		When plasmas, say streams of charged particles, interact electromagnetically, their force law varies inversely as the distance between them, 1/2 the pull if they are 2 arbitrary measurement units apart, 1/3 the pull for a distance of 3 units apart, 1/4 the pull for 4 units apart, and so on.
		So at 4 arbitrary distance units apart, the electromagnetic force is 4 times greater than that of gravitation, relatively speaking, and at 100 units, apart, the electromagnetic force is 100 times that of gravitation.

	The Four Fundamental Forces
		The strong force is by far the strongest of the forces, followed by the electromagnetic force, the weak force, and finally the extremely feeble gravitational force.
