ISBN 0-07-033183-9 8.2 A method of magnetic tests shall be chosen which causes the magnet to operate at one or more points on its major and/or minor hysteresis loops as indicated by the operating points of the magnet in its final magnetic circuit. The acceptance limits chosen shall be mutually agreeable to both the manufacturer and user. A magnet shall be chosen to serve as a calibration reference. Acceptability of a magnet will then be judged solely by comparison to the reference magnet, tested under identical conditions. 21 Magnetic Properties (nom istivity Ohm-cm x10-6 (at 20ºC) Thermal Conductivity W/(m • K) Coefficient Of Thermal Expansion 10-6/ºC 1.6/0.35 5.2/0.61 2.0/0.25 FeCr he cross sectional area of the air gap perpendicular to the flux path, is the average cross sectional area of that portion of the air gap within which the application interaction occurs. Area is measured in sq. cm. in a plane normal to the central flux line of the air gap. Am Area of the magnet, is the cross sectional area of the magnet perpendicular to the central flux line, measured in sq. cm. at any point along its length. In design, Am is usually considered the area at the neutral section of the magnet. B Magnetic induction, is the magnetic field induced by a field strength, H, at a given point.
