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. $\endgroup$ – Sebastian Riese May 11 '15 at 12:35

  • $\begingroup$ @SebastianRiese Nice, then my idea isn't hopeless after all. Might be expensive, but plausible at least. $\endgroup$ – Torxed May 11 '15 at 12:49
  • $\begingroup$ @gonenc sorry for a badly formulated question. I'm usually more verbally potent when asking questions but this field is so new to me I thought the question was clear enough. I've update my question :) $\endgroup$ – Torxed May 11 '15 at 12:50
  • $\begingroup$ As graphene is conducting electricity, you will not eliminate eddy currents. They are not a consequence of "metallicity" but of conductivity. $\endgroup$ – Sebastian Riese May 11 '15 at 14:28

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.

    $\begingroup$ Care to elaborate on the need for exfoliated graphene? $\endgroup$ – Kyle Kanos Feb 27 at 12:37
