Definition/MeaningWord/Phrase
magnet, soft iron bar linking poles of horseshoe armature , keeper
has a moving magnet and astatic coils arranged to cancel the effect of the Earth's magnetic field astatic galvanometer
magnet in the form of a bar with magnetic poles at each end bar magnet
phenomenon exhibited by materials like copper or bismuth that become magnetized in a magnetic field with a polarity opposite to the magnetic force; unlike iron they are slightly repelled by a magnet diamagnetism
generator consisting of a coil (the armature) that rotates between the poles of an electromagnet (the field magnet) causing a current to flow in the armature dynamo
temporary magnet made by coiling wire around an iron core; when current flows in the coil the iron becomes a magnet electromagnet
electric coil around a field magnet that produces the magneto motive force to set up the flux in an electric machine field coil , field winding
magnet that provides a magnetic field in a dynamo or electric motor field magnet
lines of force surrounding a permanent magnet or a moving charged particle flux , magnetic field , magnetic flux
permanent magnet consisting of magnetite that possess polarity and has the power to attract as well as to be attracted magnetically loadstone , lodestone
(computer science) a doughnut-shaped magnet formerly used to store one bit of information in the main memory of a computer; now superseded by semiconductor memories magnetic core
torque exerted on a magnet or dipole when it is placed in a magnetic field magnetic moment , moment of a magnet
slender magnet suspended in a magnetic compass on a mounting with little friction; used to indicate the direction of the earth's magnetic pole magnetic needle
one of the two ends of a magnet where the magnetism seems to be concentrated magnetic pole , pole
pole of a magnet that points toward the south when the magnet is suspended freely negative magnetic pole , negative pole , south-seeking pole
pole of a magnet that points toward the north when the magnet is suspended freely north-seeking pole , positive magnetic pole , positive pole
magnet made of a substance whose magnetization is proportional to the strength of the magnetic field applied to it paramagnet
magnet that retains its magnetism after being removed from a magnetic field permanent magnet , static magnet
coil of wire around an iron core; becomes a magnet when current passes through the coil solenoid
small permanent magnet in a metal container; when the magnet clicks against the container it indicates that the magnet is directly over an iron nail that holds the wallboard to a stud stud finder
