Industry Snapshot

According to the U.S. Census Bureau, shipments in the electronic coil, transformer and other inductor industry grew from $1.4 billion in 1999 to $1.65 billion in 2000. The cost of materials increased from $545 million to $638 million over the same time period. Employees in 2000 numbered 17,283, of whom 13,192 were production workers earning an average hourly wage of $10.38.

Background and Development

The pioneering figure in the industry was English chemist and physicist Michael Faraday (1791-1867): credited with discovering the phenomenon of electro-magnetic induction in 1831, he was also the first person to use a magnetic circuit to connect two electric circuits. In his experiments with induction, Faraday developed an early version of the transformer. The earliest patent for a power transformer was granted to C. Zipernowski, O. Blathy, and M. Deri of Budapest in 1885. Deri also received the first patent for a distribution transformer in 1885.

"Inductor" is a generic term for an electronic coil, sometimes referred to as an electronic choke. Inductors either filter or select certain frequencies within AC or pulsating DC circuits. In his Basic Electricity and Electronics, Delton T. Horn defined inductors and inductance as follows: "An inductor is a device capable of storing magnetic energy in a circuit. Typically it consists of a coil of wire around some type of core, which may be magnetic or nonmagnetic. Inductance is...
