Features:
A low cost alternative to other magnetic materials, offers relatively high operating temperatures and good resistance to corrosion & demagnetization. However, it has lower energy levels (Br) and is brittle in nature.
Applications:
Dc motors, Louderspeaks, Magnetic Separators, Automotive Sensors, Educations, etc.
