magnetic circuit [mag′ned·ik ′sər·kət] (electromagnetism) A group of magnetic flux lines each forming a closed path, especially when this circuit is regarded as analogous to an electric circuit because of the similarity of its magnetic field equations to direct-current circuit equations.

| Nd-based magnets are being used in voice coil motors of hard disk drives, magnetic circuits of medical-use magnetic resonance imagers (MRIs) and in cellular phones. But the latest generation of eddy current separators feature magnetic circuits suitable to cover material sizes ranging from 3/8-inches to six inches, and do not require that the standard material size fraction be further split into different subfraction sizes that would necessitate either different eddy current separator lines or for these different fractions to pass in different batches on the same machine with different settings. The sensor frees design engineers from having to devise and make their own magnetic circuits, and the small package size is easily implemented on a PC board. |
