Glossary of terms for the magnetics industry Select a letter: A-B-C-D-E-F-G-H-I-J-K-L-M-N-O-P-Q-R-S-T-U-V-W-X-Y-Z O Oersted The unit of magnetic field strength, H, in the cgs electromagnetic system. One oersted equals a magnetomotive force of one Gilbert per centimeter of flux path. One oersted x 0.0796 = one kA/m. Ohm Unit of electrical resistance. Open Circuit Condition Exists when a magnetized magnet is by itself with no nearby external flux path of permeable material, i.e., permeability greater than 1. Operating Line The operating line for a given permanent magnet circuit is a straight line passing through the origin of the demagnetization curve with a slope of negative Bd/Hd. Although the slope is negative, by convention the values are usually referred to in the absolute value of the slope. (Also known as permeance coefficient line.) Operating Point That point on a demagnetization curve defined by the coordinates (Bd/Hd) or that point within the demagnetization curve defined by the coordinates (Bm,Hm).
