Magnetic separation is based on the specific bonding of molecules/biomolecules/cells on magnetic nanoparticles and their removal from mixtures by a magnetic field. Although superparamagnetic nanoparticles are usually mentioned as magnetic carriers, they are not suitable for industrial use. The force acting on a single magnetic nanoparticle in a magnetic field gradient is too weak for effective ...

Ferrite (magnet) - Wikipedia

Unlike other ferromagnetic materials, most ferrites are not electrically conductive, making them useful in applications like magnetic cores for transformers to suppress eddy currents Ferrites can be divided into two families based on their resistance to being demagnetized (magnetic coercivity). Hard ferrites have high coercivity, so are difficult to demagnetize. They are used to make permanent ...

Ferrite (magnet) - Wikipedia

Composition, structure, and properties. Ferrites are usually ferrimagnetic ceramic compounds derived from iron oxides. Magnetite (Fe 3 O 4) is a famous example.Like most of the other ceramics, ferrites are hard, brittle, and poor conductors of electricity. Many ferrites adopt the spinel structure with the formula AB 2 O 4, where A and B represent various metal cations, usually including iron (Fe).

Ferrite Magnets Bunting - eMagnets

Ferrite magnets retain their magnetism; transformer ferrites only have magnetism when an electrical current passes through the surrounding coil which disappears when the current is turned off – they work in completely different ways. Ferrite magnets are hard ferrites – high Hc and Hci values; Transformer ferrites are soft ferrites – much lower Hc and Hci values.
