Electricpete, if you read any of the post to my thread I clearly wanted to know the difference between magnetic permeability and relative permeability. Thanks to all the post I've gotten a better understanding of it all. Now this is an equation between the force between and electromagnet and a...
The physical constant μ0, commonly called the vacuum permeability, permeability of free space, or magnetic constant is an ideal, (baseline) physical constant, which is the value of magnetic permeability in a classical vacuum. Vacuum permeability is derived from production of a magnetic field by...
In my initial I listed the the remanent Flux Density and Coercive Force magnitudes from Dexter Magnet Technologies. u=B/H gives you the permeabilty 1.318181818181818. Ur= u/Uo=1048975.20045582. I haven't said anything about electromagnets, but why wouldn't N5211 make a powerful electromagnet...
Hacksaw, MagMike, thank you for responding. Now, both of you have said that the relative permeability is 1.31 and/or 1.02 respectively. That is correct for the CGS systems of units where the permeability of a vacuum is defined as 1. In the SI system of units the relative permeability would be...
N5211
BHmax = 52 MGOe
Br = 14.5kG
Hci = 11.0 kOe
Hc = 10.6 kOe
U0 = .000001256636
I am working on a project with coils and electromagnets and the information above is from a B/H chart and the values for magnetic flux density and coercive force are for neodymium N5211 metal. I know that Br is...
