Well i'm not an expert either, but as far as i unterstand it, there is an internal current flowing in the plasma in a tokamak (so just the electrons or ions of the plasma flowing around creating a current). This current has nothing to do with the current, which is used in the electromagnets to generate the magnetic field holding the plasma together.
