magnetic field /mnet.k fild/ noun area of magnetic influence magnetic north /mnet.k n.θ/ noun the direction of the Earth’s mag-netic pole, to which the north-seeking pole of a magnetic needle points if unaf-fected by nearby influences magnetic pole /mnet.k p.υl/ noun one of the two poles which are the centres of the Earth’s magnetic field magnetic variation /mnet.k ve.r.e..(.)n/ noun differences in the Earth’s magnetic field in time and place . To convert magnetic bearing into true bearing it is necessary to apply mag-netic variation at the point at which the bearing was taken. Also called mag-netic declination magnetise /mn.ta.z/, magnet-ize verb to convert an object or material into a magnet . Ferro-magnetic materi-als are easily magnetised. magnetism /mn.t.z(.)m/ noun a force exerted by a magnetic field . An electric current produces magnetism, 143 maneuver and movement of a magnet can produce electricity. magneto /mnit.υ/ noun a device that produces electrical current for dis-tribution to the spark plugs of piston aero-engines COMMENT: The crankshaft turns the magnetos, which provide the electrical energy to create a spark from the spark plugs. This ensures that the spark plugs work even if the aircraft’s battery and electrical system fail. Most aircraft have two magnetos per engine in case one fails. magnify /mn.fa./ verb 1. to increase the size of, especially by using a lens, microscope, etc. . It was only after the image was magnified that it was possible to see the flaw. 2. to increase the effect of something . The stress level is magnified at times of high work load, for example, preparation for landing. (NOTE: magnifying – magni-fied) magnitude /mn.tjud/ noun greatness in size or extent . The magni-tude of the pressure gradient force is inversely proportional to the distance apart of the isobars. . When the surface wind speed reaches a particular magni-tude the term gale is used.
