magnetic powder material
1Powder coating — is a type of dry coating, which is applied as a free flowing, dry powder. The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in a… …
2Magnetic tweezers — A magnetic tweezer is a scientific instrument for exerting and measuring forces on magnetic particles using a magnetic field gradient. Typical applications are single molecule micromanipulation, rheology of soft matter, and studies of force… …
3Magnetic-particle inspection — (MPI) is a non destructive testing (NDT) process for detecting surface and subsurface discontinuities in ferroelectric materials such as iron, nickel, cobalt, and some of their alloys. The process puts a magnetic field into the part. The piece… …
4Powder diffraction — is a scientific technique using X ray, neutron, or electron diffraction on powder or microcrystalline samples for structural characterization of materials. [B.D. Cullity Elements of X ray Diffraction Addison Wesley Mass. 1978] Explanation Ideally …
5Powder metallurgy — is the process of blending fine powdered materials, pressing them into a desired shape (compacting), and then heating the compressed material in a controlled atmosphere to bond the material (sintering). The powder metallurgy process generally… …
6Magnetic core — A magnetic core is a piece of magnetic material with a high permeability used to confine and guide magnetic fields in electrical, electromechanical and magnetic devices such as electromagnets, transformers, electric motors, inductors and magnetic …
7Magnetic refrigeration — Gadolinium alloy heats up inside the magnetic field and loses thermal energy to the environment, so it exits the field cooler than when it entered. Magnetic refrigeration is a cooling technology based on the magnetocaloric effect. This technique… …
8Magnetic tape sound recording — Klaudia Wilde from the German WDR radio archive with a broadcast tape from 1990 The use of magnetic tape for sound recording originated around 1930. Magnetizable tape revolutionized both the radio broadcast and music recording industries. It did… …
9Magnetic particle clutch — A magnetic particle clutch is a special type of electromagnetic clutch which does not use friction plates. Instead, it uses a fine powder of magnetically susceptible material (typically stainless steel) to mechanically link an otherwise free… …
10Magnetic tape — 7 inch reel of ¼ inch wide audio recording tape, typical of consumer use in the 1950s–70s. Magnetic tape is a medium for magnetic recording, made of a thin magnetizable coating on a long, narrow strip of plastic. It was developed in Germany,… …
