Drolet's 1990 Rhumart system, a PEMF device. Pulsed electromagnetic field therapy ( PEMFT, or PEMF therapy ), also known as low field magnetic stimulation ( LFMS) is the use of electromagnetic fields in an attempt to heal non-union fractures and depression. [1] By 2007 the FDA had cleared several such stimulation devices.
Electromagnetic shielding is the process of lowering the electromagnetic field in an area by barricading it with conductive or magnetic material. Copper is used for radio frequency (RF) shielding because it absorbs radio and other electromagnetic waves. Properly designed and constructed RF shielding enclosures satisfy most RF shielding needs ...
t. e. In electromagnetism and electronics, electromotive force (also electromotance, abbreviated emf, [1] [2] denoted ) is an energy transfer to an electric circuit per unit of electric charge, measured in volts. Devices called electrical transducers provide an emf [3] by converting other forms of energy into electrical energy. [3]
t. e. An electromagnetic field (also EM field) is a physical field, mathematical functions of position and time, representing the influences on and due to electric charges. [1] The field at any point in space and time can be regarded as a combination of an electric field and a magnetic field. Because of the interrelationship between the fields ...
An antistatic bag is a bag used for storing electronic components, which are prone to damage caused by electrostatic discharge (ESD). These bags are usually plastic polyethylene terephthalate (PET) and have a distinctive color (silvery for metallised film, pink or black for polyethylene ). The polyethylene variant may also take the form of foam ...

Comparison of EM simulation software. The following table lists software packages with their own article on Wikipedia that are nominal EM (electromagnetic) simulators; Antenna modeling, especially in Amateur Radio. Widely used as the basis for many GUI-based programs on many platforms. Version 2 is open source, but Versions 3 and 4 are ...
Blue Shield of California is a mutual benefit corporation and health plan [6] [7] founded in 1939 by the California Medical Association. It is based in Oakland, California, and serves 4.5 million health plan members and more than 65,000 physicians across the state. Blue Shield of California was founded as a not-for-profit organization.
