Why is a dewar flask nonmagnetic?
It is made of glass and silver plate which are nonmagnetic. The plate on the glass could also be aluminum but still not affected much by an external magnetic field. As long as the flask has no iron, nickel, or cobalt (ferromagnetic elements) it would be called nonmagnetic. Note all materials are affected by a magnetic field, but it is very much a subtle effect for most things we call nonmagnetic.
Difference between pearmeability and permeability coefficient?
Permeability is part of the proportionality constant in Darcy `s law which relates discharge (flow rate) and fluid physical properties (e.g. viscosity), to a pressure gradient applied to the porous media:The proportionality constant specifically for the flow of water through a porous media is called the hydraulic conductivity; permeability is a portion of this, and is a property of the porous media only, not the fluid. Given the value of hydraulic conductivity for a subsurface system, k, the permeability can be calculated as:κ is the permeability, m2k is the hydraulic conductivity, m/sμ is the dynamic viscosity, kg/(m·s)ρ is the density of the fluid, kg/m3g is the acceleration due to gravity, m/s2.v is the superficial fluid flow velocity through the medium (i.e., the average velocity calculated as if the fluid were the only phase present in the porous medium)ΔP is the applied pressure difference (Pa)Δx is the thickness of the bed of the porous medium (m)
Is gold magnetic or non-magnetic?
Gold is nonmagnetic.
Is argon magnetic or nonmagnetic?

In science what does permeability refer to?
It has meanings in both electromagnetism and chemistry/earth sciences. Permeability in electromagnetism in means how receptive a material is to magnetization. Permeability in earth sciences can mean how well a material such as rock can transmit fluids.
Where can you use a magnet?
A magnet can be theoretically used in any medium, but strength of the magnet will strongly be influenced by the magnetic permeability of that given medium.
Can 316L stainless steel be picked up by a magnet?
316L stainless steel is considered "nonmagnetic", but you shouldn't count that any individual piece will be. Cold working or welding can dramatically increase the magnetic permeability of the material.
The speed of light depends on?
... the electrostatic permittivity and the magnetic permeability of the medium. As a matter of fact, the speed of light in the medium is the reciprocal of the square root of their product.
What is the permeability of iron?
A stable, nonmagnetic austenitic alloy steel having extremely low magnetic permeability especially in the unannealed condition, and consisting essentially of, in percent by weight, carbon 0.35 to 0.45, manganese 14 to 16.5, phosphorus 0.05 max., sulfur 0.07 to 0.12, silicon 0.55 to 1.15, nickel 3.5 to 5.5, nitrogen 0.12 max., chromium, 0.50 max. and the balance iron and incidental impurities.
When electromagnetic waves are moving through matter the speed of electromagnetic waves depends on?
Velocity of light in a medium depends on the electric and magnetic properties of that medium, namely permittivity, and permeability.
What feature of a membrane describes whether molecules can cross the membrane?
