Low Permeability Material
Low Permeability Material
(OP)
Hi All,
I am looking for a magnetic material having a low relative permeability in the range of 10-100. I had search in the site, but no one I found.
Would you help me?

RE: Low Permeability Material
Also, Alnico permanent magnets have low relative permeabilities as well.
Keep in mind, materials with low permeabilities will generally have large hysteresis losses.
It sounds like you have an interesting application. Can you describe what you have in mind?
RE: Low Permeability Material
In general, metallic material for magnetic applications are usually optimized for maximum perm., usually greater than 300 and can be many thousands. Metallic material, in the range you are interested in, are usually not magnetically characterized or controlled.
Depending on the flux density, I would suggest looking at the various grades of ferrite material.
RE: Low Permeability Material
I am working in the permanent magnet generator design.
I faced a problem in flux fringing. Utilizing the low permeability material as additional component, I hope it will solve the problem. The high permeability material will disturb the main flux.
Thanks for your suggestion and help.
