Fundaments
• The origin of magnetism is due the electron spin
B = μ(H + M) B = Magnetic Induction T Gauss
H = Magnetic Field Am2 OeM = Magnetic Saturation Am2 emu/cm3
= Material Permeability Henry/ m.
*M o J = Intensity magnetization

Actual Process Barium Ferrite
• Nowadays the Barium Ferrite is obtained by:
1. Ceramic
2. Co precipitation
3. SOL-GEL
The highest Magnetic Saturation is about 0.475 T [Stäblein]
