Designing Magnetic Circuits Magnet Man Cool
2016-11-26 Designing Magnetic Circuits. Designing circuits with magnetic fields is very similar to designing electrical circuits. With simple electrical circuits, we use an EMF (voltage source) and resistors, and can determine how much current will flow. Similarly, for magnetic circuits, we use an MMF and reluctance of materials, and can determine how
