The relationship between magnetic and electrical fields provides the foundational theory for the flow of electricity. While naturally occurring electrical phenomenon such as lightning, static electricity and the shocks of various fishes have been observed in the ancient world, the formal study and understanding of electric phenomenon began with William Gilbert's work on static electricity in the 1600s. The 1700s would see Benjamin Franklin's many significant discoveries and Luigi Galvani's discovery of bioelectricity, and in the early 1800s André-Marie Ampère and Hans Christian Ørsted discovered the link between electricity and magnetism, which were formalized by Maxwell's laws in 1873. These laws form the mathematical basis for practically the entire field of electrical engineering and its developments. The pure fields and waves aspects are still very commonly used today in applications such as antennas, microwaves and radio astronomy.

The IEEE Antennas and Propagation Society, IEEE Electromagnetic Compatibility Society, IEEE Magnetics Society, IEEE Microwave Theory and Techniques Society publish technical journals related to electromagnetic fields and waves.
