Permeability of copper wire
WebPermeability is represented by μ. The high permeability makes mu-metal very effective at screening static or low-frequency magnetic fields, which cannot be attenuated by other methods. Mu metal requires special heat treatment — annealing in hydrogen atmosphere, which reportedly increases the magnetic permeability about 40 times. In the macroscopic formulation of electromagnetism, there appears two different kinds of magnetic field: • the magnetizing field H which is generated around electric currents and displacement currents, and also emanates from the poles of magnets. The SI units of H are amperes/meter. • the magnetic flux density B which acts back on the electrical domain, by curving the motion of charges and cau…

WebJun 16, 2024 · As far as the copper conductors are concerned, THHN is identical to the Prestolite. Both are comprised of 19 strands of 29 AWG wire. The difference between the two products comes down to the insulation/jacketing: Prestolite uses CPE that is 57 mils thick. CPE has a dielectric constant of 5.5 THHN uses PVC that is 4 mils thick. http://info.ee.surrey.ac.uk/Workshop/advice/coils/air_coils.html
