What physical property of material refers to the rate of heat flow per unit time in a homogeneous material under steady state conditions per unit area, unit temperature gradient in a direction perpendicular to the area? a. Thermal expansion . b. Thermal conductivity . c. Heat distortion temperature . d. Water absorption WebbFor permanent magnet the first breaks down (fields are constantly there and are not "low") and the second very quickly with increasing frequency. So for a magnetized magnet a permeability based model makes no sense. One can specify a permeability for the (unmagnetized) material the magnet is made of, though. This is probably what you saw.

In electromagnetism, permeability is the measure of magnetization that a material obtains in response to an applied magnetic field. Permeability is typically represented by the (italicized) Greek letter μ. The term was coined by William Thomson, 1st Baron Kelvin in 1872, and used alongside permittivity by Oliver Heaviside in 1885. The reciprocal of permeability is magnetic reluctivity. grand bahama all inclusive hotelsWebb1 apr. 2024 · Permittivity varies significantly as a function of frequency.
