What is the maximum surface magnetic field of injection molded ferrite magnets in Gs?

Generally ranging from 1200 Gs to 1300 Gs, subject to specific dimensions. Certain sizes can reach 1500–1700 Gs.

Below are test data of our samples for reference:

Radial outer 10-pole injection molded ferrite magnet, D40.5×28.5×26; average peak surface magnetic field: 1600±80 Gs.

Radial outer 4-pole, D27.80×24.85×26.5; surface magnetic field: 1450 Gs.

Radial inner 4-pole, D40×31×12; magnetic strength: 850–900 Gs.

Injection molded magnet, radial outer 8-pole, D74×62×30; magnetic strength: 1750 Gs.

If superior magnetic performance is required, injection molded NdFeB magnets are recommended. They deliver much stronger magnetic properties than injection molded ferrite magnets, yet come with a relatively higher cost.
