They are composed of iron oxide and strontium carbonate.
Ceramic vs moving magnet.

A moving magnet mm cartridge is the most common type of phono cartridge.
2 the moving magnet cartridge.
The grooves cause the stylus to vibrate which disrupts the magnetic field and generates an electric signal in the wire coils.
Unlike a ceramic cartridge the back end of the stylus in a magnetic cartridge is not embedded in a block of material.
In high fidelity systems crystal and ceramic pickups have been replaced by the magnetic cartridge using either a moving magnet or a moving coil.
Unlike ceramic cartridges there is no or much less physical connection between the stylus the magnet and the wire coils.

As the stylus moves the magnets change their relationship with the coils in the body of the cartridge which generates a small voltage.
The two coils are attached to the cantilever and move within the field of a fixed permanent magnet to form the electrical generator.
Ceramic cartridge underside view showing stylus cartridge type no.
This type works completely different than the ceramic cartridge.
Ceramic vs moving magnet manufacturers factory suppliers from china we are keeping durable business relationships with more than 200 wholesalers in the usa the uk germany and canada.
A moving coil mc design works in the opposite way by allowing the cantilever to vibrate coiled wires near fixed magnets.
Magnetic cartridges moving coil and moving magnet work on this principle.
This video features a sound test of ceramic and magnetic turntable pickup cartridges.
What is a ceramic magnet ceramic magnets also known as ferrite magnets were developed in the 1960 s as a low cost alternative to metallic magnets.
Compared to the crystal and ceramic pickups the magnetic cartridge usually gives improved playback fidelity and reduced record wear by tracking the groove with lighter pressure.
