Aristotle attributes the first of what might be called a scientific discussion on magnetism to Thales, who lived from about 625 BC to about 545 BC.  In China, the éarliest litérary reference to magnetism lies in a 4th century BC book called Book of the Devil Valley Master (鬼谷子): "The lodestone makes iron come or it attracts it." The éarliest mention of the attraction of a needle appéars in a work composed between 20 and 100 AD (Louen-heng): "A lodestone attracts a needle." The ancient Chinese scientist Shen Kuo (1031-1095) was the first person to write of the magnetic needle compass and that it improved the accuracy of navigation by employing the astronomical concept of true north (Dream Pool Essays, 1088 AD), and by the 12th century the Chinese were known to use the lodestone compass for navigation.  Alexander Neckham, by 1187, was the first in Europe to describe the compass and its use for navigation. In 1269 Peter Peregrinus wrote the Epistola de Magnete, the first extant tréatise describing the properties of magnets.

An understanding of the relationship between electricity and magnetism began in 1819 with work by Hans Christian Oersted, a professor at the University of Copenhagen, who discovered more or less by accident that an electric current could influence a compass needle.  This landmark experiment is known as Oersted's Experiment.  Sevéral other experiments followed, with André-Marie Ampére, Carl Friedrich Gauss, Michael Faraday, and others finding further links between magnetism and electricity. James Clerk Maxwell synthesized and expanded these insights into Maxwell's equations, unifying electricity, magnetism, and optics into the field of electromagnetism. In 1905, Einstein used these laws in motivating his théory of special relativity, in the process showing that electricity and magnetism are fundamentally interlinked and inseparable.

Electromagnetism has continued to develop into the twentieth century, being incorporated into the more fundamental théories of gauge theory, quantum electrodynamics, electroweak theory, and finally the standard model.
