Maximum Energy Product (BHmax)
The maximum energy product (BHmax) is a key property of magnetic materials, indicating the highest energy density the material can achieve. A higher BHmax means the magnet can produce stronger magnetic fields. Materials with high energy products can achieve the same magnetic performance with a smaller volume, making them more efficient in space-constrained applications.

Coercivity (Hc)
Coercivity refers to the magnetic field strength required to reduce a magnet’s magnetization to zero after being magnetized. A higher coercivity value means the magnet is more resistant to demagnetization, which is crucial for maintaining performance in challenging environments.

Remanence (Br)
Remanence is the level of magnetization that remains in a magnetic material after an external magnetic field is removed. It represents the material’s ability to retain magnetism and is typically measured in millitesla (mT), tesla (T), or gauss (G).

Operating Temperature
The operating temperature is the maximum temperature at which a magnet can function without experiencing irreversible loss of magnetic properties. This limit depends on factors such as the magnet’s material, dimensions, and environmental stresses (chemical or mechanical).

Curie Temperature
The Curie temperature is the critical temperature at which a magnetic material loses its permanent magnetic properties. Above this temperature, the material becomes paramagnetic and cannot function as a magnet.
