To energize or excite (the field magnets of a dynamo) by induction from the residual magnetism of its cores, leading all or a part of the current thus produced through the field-magnet coils.

An induction coil, esp. of an internal-combustion engine, wireless telegraph apparatus, etc.

air or other dielectric between high potential terminals (as of an electrostatic machine, induction coil, or condenser), through which the discharge passes; the air gap of a jump spark.

d into the cylinder head, having through it an insulated wire which is connected with the induction coil or magneto circuit on the outside, and forms, with another terminal on the base of the plug, a spark gap inside the cylinder.

nductive capacity (Physics), the effect of a dielectric body in producing static electric induction as compared with that of some other body or bodies referred to as a standard. -- Specific legacy (Law), a bequest of a particular thing, as of a particular animal or piece of furniture, specified and distinguished from…

Superinduction.

minute selenium cells. The receiver includes an oscillograph, ralay, equilibrator, and an induction coil the sparks from which perforate a paper with tiny holes that form the image.

, patented in March, 1897. Marconi employed electric waves of high frequency set up by an induction coil in an oscillator, these waves being launched into space through a lofty antenna. The receiving apparatus consisted of another antenna in circuit with a coherer and small battery for operating through a relay the ord…
