E2 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 transfers the mechanical vibrations picked up from the record groove by the stylus directly into the permanent magnet. The changing magnetic field it produces induces a magnetic “flow” through the pole shoes which, in turn, generates an e.m.f in the fixed coils in direct proportion to the mechanical vibration. In this way, the sound wave captured as undulations in the record grooves has been converted into a tiny electrical signal which can then be amplified and converted back into sound by the speakers.

The coil must be connected to a special phono amplifier input via the turntable leads so that the low voltage generated by the cartridge (typically 5 mV) is boosted to several volts to drive the speakers. All MM cartridges have a relatively high output and require a 47 k load impedance for current to flow making them compatible with the basic phono input found as standard on many integrated amplifiers. If your amplifier does not feature a MM phono input, these can be purchased separately at a reasonable cost.



The Goldring philosophy is to promote the accurate replication of the original record production, maintaining the creative nuances, musicality and rhythm the artist intended you to hear. With the versatile E Series, this is easy to achieve with all three cartridges in the range; each is designed to be simple to fit to the majority of budget to medium priced turntables with little or no fuss .



For the highest accuracy and most detailed listening experience we offer a selection of excellent moving coil cartridge designs. With the lowest moving mass and most advanced diamond profiles, Goldring's innovative, hand-made MC cartridges offer the best performance for the most discerning listeners.
