High Flux Core for Energy Storage Reactor

High Flux Core for Energy Storage Reactor

Magnetic material is mainly classified as permanent ferromagnetic material and soft ferromagnetic material. Permanent ferromagnetic material is also called hard ferromagnetic material; the material can keep the strong magnetic force after applying an external magnetic field.

G&M is able to customize the design to meet customers’ requirements.

Magnetic material is mainly classified as permanent ferromagnetic material and soft ferromagnetic material. Permanent ferromagnetic material is also called hard ferromagnetic material; the material can keep the strong magnetic force after applying an external magnetic field. The characteristic is high coercivity (Hc). Typical coercivity is Hc>103A/m, BHmax is high. Soft ferromagnetic material will be magnetized after applying an external magnetic field but it will lose the magnetics force easily. Characteristic is low coercivity, typical Hc<103A/m
