reactor an electrical device used to introduce reactance into a circuit
armature coil in which voltage is induced by motion through a magnetic field
astatic coils an arrangement of coils used in sensitive electrical instruments; the coils are arranged to give zero resultant external magnetic field when a current passes through them and to have zero electromotive force induced in them by an external magnetic field
field coil,
field winding the electric coil around a field magnet that produces the magneto motive force to set up the flux in an electric machine
induction coil a coil for producing a high voltage from a low-voltage source
primary coil,
primary winding,
primary coil forming the part of an electrical circuit such that changing current in it induces a current in a neighboring circuit; "current through the primary coil induces current in the secondary coil"
read/write head,
head (computer science) a tiny electromagnetic coil and metal pole used to write and read magnetic patterns on a disk
