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 G Gap Compound An adhesive applied to the gap surfaces of C and E -cores to reduce mechanical noise levels. On small cores, it occasionally is used instead of banding to hold the two halves together. Gauss The unit of magnetic induction, B, in the CGS electromagnetic system. One gauss is equal to one maxwell per square centimeter or 10-4 tesla. Gauss-Oersted See energy product and maximum energy product (BHmax). Gaussmeter An instrument that measures the instantaneous value of magnetic induction, B. Its principle of operation is usually based on one of the following: the Hall effect, nuclear magnetic resonance (NMR), or the rotating coil principle. Gilbert A unit of magnetomotive force, F, in the CGS system. Graded Cores MPP and HF cores are graded into increments of permeability within their normal ± 8% tolerance. It is expressed as a per cent deviation from the nominal value. Grain Oriented Silicon steel or other granular magnetic material that has a preferred direction of magnetization. Ground Fault Indicator A device that detects very low-level currents in the neutral conductor of an electrical line. This requires a very high-permeability core; generally Ni-Fe alloys are used.
