So it's probably a quick no on this one, but since I haven't majored in physics or chemistry I have no idea if it's possible to make Graphene generate a magnetic field.

Assuming power or current is no problem. Having a small PCB made out of graphene components, will they generate magnetic currents? If so, can they become strong enough that you could build a electro magnet?

What I would like to do is simply replace the copper rotor of a DC brushless motor with a 3d printed graphene disc and/or replace the stator of the motor. If graphene can generate magnetic fields this should be possible right?

I guess what i'm also asking is if it's possible to induce magnetic fields in a carbon structure such as graphene which will be used to eliminate eddy currents within the rotor.

Thank you in advance //Anton

    $\begingroup$ How would this solve headaches? And what do you mean with "generate a magnetic field". If a current flows through a graphene solenoid, it will surely create a magnetic field. $\endgroup$ May 11 '15 at 12:35

    $\begingroup$ As graphene is conducting electricity, you will not eliminate eddy currents. They are not a consequence of "metallicity" but of conductivity. $\endgroup$ May 11 '15 at 14:28

    $\begingroup$ Could you be more specific about the motor design? (I don't fully understand the one you linked), I know motors with passive rotors (which are in modern applications neodymium magnets), motors with active rotors (and active or passive stators) and a commutator and asynchronous motors. How does your intended motor design fit in these coordinates. Furthermore I guess the point of steel in the design is that steel is ferromagnetic, graphene is not (or not in a useful way for something like this). Especially as steel would not be the material of choice where conductivity is relevant. $\endgroup$ May 12 '15 at 0:36

    $\begingroup$ Note that there is no such a thing as "magnetic current", that would imply there exist magnetic monopoles and those have not been found to date. $\endgroup$

yeah it should do. as long as the material is conductive, it will induce a magnetic field. the problem is that you need exfoliated graphene which is hard to produce. once mass production of it starts, it will easily replace copper solenoids.
