ferromagnetic materials
31Magnetostriction — Animation of magnetostriction Magnetostriction (cf. electrostriction) is a property of ferromagnetic materials that causes them to change their shape or dimensions during the process of magnetization. The variation of material s magnetization due …
32Barkhausen effect — The Barkhausen effect is a name given to the noise in the magnetic output of a ferromagnet when the magnetizing force applied to it is changed. Discovered by German physicist Heinrich Barkhausen in 1919, it is caused by rapid changes of size of… …
33Negative index metamaterials — A negative index metamaterial causes light to refract, or bend, differently than in more common positive refractive index materials. Negative index metamaterials or negative index materials (NIM) are artificial structures where the refractive… …

35Tubular NDT — (nondestructive testing) is the application of various technologies to detect anomalies such as corrosion and manufacturing defects in metallic tubes. Tubing can be found in such equipment as boilers and heat exchangers. To carry out an… …
36electromagnetism — /i lek troh mag ni tiz euhm/, n. 1. the phenomena associated with electric and magnetic fields and their interactions with each other and with electric charges and currents. 2. Also, electromagnetics. the science that deals with these phenomena.… …
37Permeability (electromagnetism) — Magnetic Circuits Conventional Magnetic Circuits Magnetomotive force Magnetic flux Φ Magnetic reluctance Phasor Magnetic Circuits Complex reluctance Zμ …
38Magnetic domain — Several grains of NdFeB with magnetic domains made visible via contrast with a Kerr microscope. A magnetic domain describes a region within a magnetic material which has uniform magnetization. This means that the individual magnetic moments of… …
39Ferrite (magnet) — For other uses, see Ferrite (disambiguation). A stack of ferrite magnets Ferrites are chemical compounds consisting of ceramic materials with iron(III) oxide (Fe2O3) as their principal component.[1] Many of them are magnetic materials and t …
