Soft Ferrites are not permanent magnets. They carry magnetism (like mild steel) but as soon as the magnetic field is removed, the magnetism disappears. Soft Ferrites are popular as transformers (to change the voltage from primary to secondary windings). Soft Ferrites are often called transformer Ferrites.
Soft Ferrites exist as toroids (rings), C shapes, E-shapes, curved shapes, etc. Other shapes are possible. They often have performance criteria such as permeability and inductance.
