Magnets and their uses


magnets and their uses

the cores of RF transformers and inductors in applications such as switched-mode power supplies and loopstick antennas used in AM radios. They play an important role in a wide range of devices including simple toys, computers, credit cards, MRI machines and business equipment. Spinel ferrites usually adopt a crystal motif consisting of cubic close-packed (fcc) oxides (O2) with A cations occupying one eighth of the tetrahedral holes and B cations occupying half of the octahedral holes,.e., A2 B3 2O2. 51,., 1980 Raul Valenzuela, Magnetic Ceramics,. MRIs use powerful magnetic fields to generate a radar-like radio signal from inside the body, using the signal to create a clear, detailed picture of bones, organs and other tissue.

The chemical composition and especially the structure vary strongly between the precursor and the sintered product. The dark magnetic strip on the backside of a credit card stores data in much the same way as a computers hard drive does. An MRI magnet is very strong thousands of times more powerful than common kitchen magnets. 4 Barium ferrite, BaFe12O19 (BaO6Fe2O3 a common material for permanent magnet applications. The magnetic material known as "ZnFe" has the formula ZnFe2O4, with Fe3 occupying the octahedral sites and Zn2 occupy the tetrahedral sites, it is an example of normal structure spinel ferrite. Browse our Products, we carry hundreds of magnets in many sizes and shapes, great deals on magnet wire, plus a variety of new and antique experimental science books, magnet science tools, supplies, and test equipment, and hard-to-find components for the Renewable Energy enthusiast.

On discovering that it was actually a magnetic material, and confirming its structure by X-ray crystallography, they passed it on to the magnetic research group.
