MACHINE KEYINGA method of cw keying using punched tape or other mechanical means to key a transmitter [12]. | ||
MAGIC TSee BALANCED MIXER [18]. | ||
MAGIC-T JUNCTIONA combination of H-type and E-type T-junctions [11]. | ||
MAGNET WIREWire coated with an enamel insulation and used in coils, relays, transformers, motor windings, and so forth [4]. | ||
MAGNETIC FIELD(1) The region in which the magnetic forces created by a permanent magnet or by a current-carrying conductor or coil can be detected [1] [2]. (2) The field that is produced when current flows through a conductor or antenna [10] [11]. | ||
MAGNETIC INDUCTION Generating a voltage in a circuit by the creation of relative motion between a magnetic field and the circuit. The relative motion can be the result of physical movement or the rise and fall of a magnetic field created by a changing current [5]. | ||
MAGNETIC LINES OF FORCEImaginary lines used for convenience to designate the direction in which magnetic forces are acting as a result of magnetomotive force [2]. | ||
MAGNETIC MICROPHONEA microphone in which the sound waves vibrate a moving armature. The armature consists of a coil wound on the armature and located between the pole pieces of a permanent magnet. The armature is mechanically linked to the diaphragm [12]. | ||
MAGNETIC POLESThe section of a magnet where the flux lines are concentrated; also where they enter and leave the magnet [1]. | ||
