Physical Properties: Magnetic permeability units #464

Closed lheagy closed 7 years ago

I think this statement is potentially quite confusing: The correct SI units for magnetic susceptibility are (A/m)/(A/m). However, it is commonly expressed as a unitless quantity. http://em.geosci.xyz/content/physical_properties/magnetic_permeability/magnetic_permeability_units.html

(A/m) / (A/m) is unitless. Is there another point trying to be made here? Otherwise, I think this should be revised to simply state that Magnetic susceptibility is unitless

thoughts @fourndo, @dccowan ?

SI units for susceptibility are (A/m)/(A/m). This is another way of re-enforcing the fact that it is the magnetization/field. We write it as unitless out of convenience. This was something Randy was adamant about when I was writing up my thesis.
