isotropic dry type ferrite magnet

Isotropic magnets are sintered permanent magnets composed of barium ferrite or strontium ferrite. This class of magnets aside from good resistance to demagnetization, has the popular advantage of low cost.

Due to their low cost, isotropic magnets enjoy a very wide range of application, from motor dynamo, toys, novelty.
Their magnetic properties are listed as below:
BA-1: (Barium Ferrite)
Br>=2100Gs, bHc>=1800 Oe, iHc>=3000, (BH)max>=1.0 MGOe
SA-1: (Strontium Ferrite)
Br>=2100Gs, bHc>=1800 Oe, iHc>=3000, (BH)max>=1.0 MGOe
