MAGNETIC TRIP ELEMENTA circuit breaker trip element that uses the increasing magnetic attraction of a coil with increased current to open the circuit [3]. |
MAGNETISMThe property possessed by certain materials by which these materials can exert mechanical force on neighboring masses of magnetic materials and can cause currents to be induced in conducting bodies moving relative to the magnetized bodies [1]. |
MAGNETRON OSCILLATORAn electron tube that provides a high power output. Theory of operation is based on interaction of electrons with the crossed electric and magnetic fields in a resonant cavity [18]. |
MAINTENANCEWork done to correct, reduce, or counteract wear, failure, and damage to equipment [16]. |
MAJOR LOBEThe lobe in which the greatest amount of radiation occurs [10]. |
MAJORITY CARRIERSThe mobile charge carriers (hole or electron) which are predominate in a semiconductor material; for example, electrons in an N-type region [7]. |
MARCONI ANTENNAA quarter-wave antenna that is operated with one end grounded and is positioned perpendicular to the earth [10]. |
MARKAn interval during which a signal is present. Also the presence of an RF signal in cw keying. The key-closed condition (presence of data) in communications systems [12]. |
MARKINGThe state where a circuit is closed and current flows in teletypewriter operation [17]. |
MASKA device used to deposit materials on a substrate in the desired pattern [14]. |
