magnetic circuit (plural magnetic circuits)
(electromagnetism) A closed path of magnetic flux.
It was powered by two Siemens & Halske alternators rated 30 hp (22 kW), 2000-V at 120 Hz and used 200 series-connected Gaulard 2000-V/20-V step-down transformers provided with a closed magnetic circuit, one for each lamp. Source: Internet
Other improvements include the use of electrical discharge machining to produce complex, three-dimensional hammers that trade-off the magnetic circuit, mechanical resonances, and printing speed. Source: Internet
Prewound copper coils could then be slid into place, and straight iron plates laid in to create a closed magnetic circuit. Source: Internet
Recent designs have performed complex optimizations in the magnetic circuit, and eliminated unwanted resonances in the spring. Source: Internet
The size and type of magnet and details of the magnetic circuit differ, depending on design goals. Source: Internet
