Is there any material that is NOT conductive and IS magnetically attractive? Is there any material which is NOT conductive and IS magnetically attractive?
I am in need of a material which I can shape and use within a machine.
It must be very attracted to magnets similarly to steel or iron.
However it must be extremely electrically resistive, like plastic insulators or ceramic insulators.
Specifically, when a magnet is passed over the material the magnet should be very attracted to it, yet the material should not produce any internal electromagnetic eddy currents and cause electromagnetic braking.
I am currently considering an epoxy solution saturated with iron filings or BBs, but I am concerned they may touch each other within the solution and create large enough conductive sections that would allow the creation of electromagnetic eddy currents. Or might not be saturated enough to allow the high magnetic attraction required.
I would prefer a solid material to allow shaping for use as a part within a motor.
Also, superconductors are not an option.
 A: Yes, ferrite. According to page 8 of this brochure, Ferrite-NiZn has a resistivity of 10^4 Ohm·m. This is better than damp wood, at least. You can trade magnetic properties for resistivity by coating and embedding ferrite pellets in an insulator, as suggested in the comment above, but fashioning your own metamaterial will probably involve quite a bit of research and experimentation.
A: Not sure if this helps but I found some pads with the stickum on the back (peel and stick) would of bet my life they were rubber(even cut a piece out to make a new bottom of my sanding block which works great)....then I noticed a magnet stuck to it like steel (very flexible 1/16" thick pad can bend 180° and doesn't break until the bend is about 1/4th" apart)
I decided to check and it is absolutely non conductive
This is how I found your post trying to figure out what material it is.
It comes from a wi-fi ,microwave,and other frequencies company.
I wish I could post a pic
A: Other materials that go in this category would be:


*

*Soft magnetic composite (SMC)

*Amorphous iron


SMC is a composite of small(microscopic) ferromagnetic particles which are coated with some kind of plastic. It can be formed into almost any shape and it isn't laminated. The ferromagnetic properties aren't as good as with other materials, but it has a permeability which is the same in every direction (not true for laminated steel, as the normal to the lamination surface will have lower permeability due to insulation layers). (not cheap, but cheaper than amorphous)
Amorphous iron on the other hand is made by a specific process where ferromagnetic particles are cooled down very fast (a few thousand Kelvin per second, as far as I remember). The structure isn't crystalline but amorphous, so it is basically a kind of glass. The conductivity is very low, and the magnetic properties are (to a good degree) retained. (Expensive stuff!).
