  • Proximity effect (electromagnetism) — In a conductor carrying current, if currents are flowing through one or more other nearby conductors, such as within a closely wound coil of wire, the distribution of current within the first conductor will be constrained to smaller regions. The… …   Wikipedia

  • Electromagnetic radiation and health — Electromagnetic radiation can be classified into ionizing radiation and non ionizing radiation, based on whether it is capable of ionizing atoms and breaking chemical bonds. Ultraviolet and higher frequencies, such as X rays or gamma rays are… …   Wikipedia

  • Electromagnetic compatibility — (EMC) is the branch of electrical sciences which studies the unintentional generation, propagation and reception of electromagnetic energy with reference to the unwanted effects (Electromagnetic Interference, or EMI) that such energy may induce.… …   Wikipedia

  • Electromagnetic clutch — Electromagnetic clutches operate electrically, but transmit torque mechanically. This is why they used to be referred to as electro mechanical clutches. Over the years, EM became known as electromagnetic versus electro mechanical, referring more… …   Wikipedia

  • Electromagnetic Formation Flight (EMFF) — investigates the concept of using electromagnets coupled with reaction wheels in place of more traditional propulsion systems to control the positions and attitudes of a number of spacecraft in close proximity. Unlike traditional propulsion… …   Wikipedia

  • Proximity sensor — A proximity sensor is a sensor able to detect the presence of nearby objects without any physical contact. A proximity sensor often emits an electromagnetic or electrostatic field, or a beam of electromagnetic radiation (infrared, for instance),… …   Wikipedia

  • Electromagnetic forming — A pinched aluminium can, produced from a pulsed magnetic field created by rapidly discharging 2 kilojoules from a high voltage capacitor bank into a 3 turn coil of heavy gauge wire. Electromagnetic forming (EM forming or magneforming) is a type… …   Wikipedia

  • Proximity card — A proximity card A proximity card controlled turnstile …   Wikipedia

  • Conducted electromagnetic interference — EMI Electromagnetic Interference: EMI is unwanted effects in the electrical system due to electromagnetic radiation and electromagnetic conduction. Electromagnetic radiation and electromagnetic conduction are differentiated by the way an EM field …   Wikipedia

  • Magnetic proximity fuze — A Magnetic proximity fuze was patented by P.J. Eliomarkakis, (United States Patent US2434551 of January 13, 1948) [1] although similar devices had been in service for nearly a decade. It is a type of proximity fuze that initiates a detonator in a …   Wikipedia
