1.1 This specification covers technically important, commercially available, magnetically hard sintered ferrite permanent magnets. 1.2 Ferrite permanent magnets have residual induction Br from 0.2 T (2000 G) up to about 0.5 T (5000 G) and intrinsic coercive field...
1.1 This specification covers technically important, commercially available, magnetically hard, cast and sintered permanent magnets known commonly as Alnico. 1.2 Alnico magnets have approximate magnetic properties of residual magnetic induction, Br, from 0.52 T (5200 G) to 1.35...
The purpose of this Standard is to define the method of measurement of the magnetic flux density, magnetic polarization and the magnetic field strength and also to determine the demagnetization curve and recoil line of permanent magnet materials, the properties of which are presumed...
This specification covers one type of loudspeaker, designated loudspeaker, permanent magnet, LS-211/AIC-13. This loudspeaker is a horn type unit with a frequency response of 200-7,000 Hz, nominal 16 ohms voice coil impedance, and a 20 watt peak power output (see 6.1).
This specification applies to technically important, commercially available, magnetically hard sintered (fully dense) permanent magnets commonly known as samarium cobalt (SmCo). SmCo permanent magnets are available in two general composition families abbreviated "SmCo...
