WebPermeability, µ. Measured H/m. This is a characteristic of the core material, and it is the rate at which magnetizing force H (driven by current) produces flux density B (integrated voltage). It is the slope of the B-H curve.Designers use high permeability material to enable physically smaller inductors and transformers. Saturation flux ... 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… marlin 12 gauge shotgun

WebA large DC inductor is often limited by the core’s saturation point. The core must be large enough in size and low enough in permeability to avoid saturation (or shift in inductance below the minimum required level.) These factors increase the turns and length of copper required, causing wire loss to become an issue.
