Ferrite Magnets For Speakers

Ferrite magnet for speakers is a ring magnet whose basic construction consists of a ferrite material and a coil.Ferrite is a magnetic ceramic material with good magnetic permeability and magnetic saturation strength, so it is often used to make magnets.The coil is a magnetic field generator wound with a conductor wire, which can generate a magnetic field after being energized.

Ferrite magnets for speakers are characterized by uniform magnetic field strength, and the direction of the magnetic field is perpendicular to the cross section of the magnet.It is widely used in research in the fields of biomedicine, materials science, and physics, such as magnetic resonance imaging (MRI), magnetic fluid separation, magnetic probes, etc.

Ferrite magnets for speakers, made by molding powder mixture of about 80% Fe2O3 and about 20% either BaCo3 or SrO3, is also called ceramic magnet.Along with deepening of research, some additives such as cobalt (Co) and lanthanum (La) are mixed together to improve the magnetic performance.The molded powder metallic green is sintered inside a temperature controlled furnace what is heated with electricity or coal. Though Hard Ferrite magnet is with low magnetic property,it is still a preferable choice to engineer in their design due to several factors: abundantly available raw material,the cheapest cost among permanent magnet family,low density,excellent stability of chemistry,high maximum working temperature and Curie temperature.
