Wikipedia

  1. Magnetic core

    A magnetic core is a piece of magnetic material with a high magnetic permeability used to confine and guide magnetic fields in electrical, electromechanical and magnetic devices such as electromagnets, transformers, electric motors, generators, inductors, magnetic recording heads, and magnetic assemblies. It is made of ferromagnetic metal such as iron, or ferrimagnetic compounds such as ferrites. The high permeability, relative to the surrounding air, causes the magnetic field lines to be concentrated in the core material. The magnetic field is often created by a current-carrying coil of wire around the core. The use of a magnetic core can increase the strength of magnetic field in an electromagnetic coil by a factor of several hundred times what it would be without the core. However, magnetic cores have side effects which must be taken into account. In alternating current (AC) devices they cause energy losses, called core losses, due to hysteresis and eddy currents in applications such as transformers and inductors. "Soft" magnetic materials with low coercivity and hysteresis, such as silicon steel, or ferrite, are usually used in cores.

  1. magnetic core

    A magnetic core is a piece of magnetic material, usually ferrite, iron, or iron-based alloy, used to confine and guide magnetic fields in electrical, electromagnetic, and magnetic devices, such as transformers and inductors. It concentrates the magnetic field, increasing the efficiency of the device by reducing the volume of material required to conduct the magnetic field.

The high permeability, relative to the surrounding air, causes the magnetic field lines to be concentrated in the core material. The magnetic field is often created by a coil of wire around the core that carries a current. The presence of the core can increase the magnetic field of a coil by a factor of several thousand over what it would be without the core. The use of a magnetic core can enormously concentrate the strength and increase the effect of magnetic fields produced by electric currents and permanent magnets. The properties of a device will depend crucially on the following factors: ⁕the geometry of the magnetic core. ⁕the amount of air gap in the magnetic circuit. ⁕the properties of the core material. ⁕the operating temperature of the core. ⁕whether the core is laminated to reduce eddy currents.
