WebInductance is directly proportional to permeability. If we increase permeability, we increase inductance. Let’s consider the air core inductor. Air has a relative permeability of 1 (μ = 1). This is because air, much like ceramic, has virtually no magnetic properties, and thus it does not enhance the coil’s inductance in any way. WebApr 4, 2024 · Here, NPs of differing physical properties, namely, electrical conductivity and relative magnetic permeability, are added to a base fluid—water in this case—which forms a nanofluid (hereby denoted as “NF”) since bulk fluid properties may also be heightened by adding different NP properties. This works examines these possibilities using a recently …
WebMar 19, 2024 · Obviously, if permeability (µ) in the equation is unstable, then the inductance (L) will also be unstable to some degree as the current through the coil changes in …
