Wat is a Moving Magnet Cartridge?
What is a Moving Magnet Cartridge? All transducers of this type depend on Faraday's Law of electromagnetic induction which implies that a conductor placed in a varying magnetic field will have an electromotive force, or e.m.f., induced in it proportional to the rate of change of the field. If a permanent magnet is suspended at or near the poles of a coil with an iron core, the coil will experience the required variable magnetic flux if the magnet is moved. A cantilever...
