Generating magnetic field with Plasma

[CognitiveNet]

If I wanted to generate plasma to replicate the magnetic flux density of a i.e. N42 magnet, what would be the required volume of gas/plasma to achieve this? This magnet has a pull force of 12kg at the contact surface.

I have chosen to use Helium, because it has the highest ionization energy level.

You just need to give me a rough estimation, by using common sense.

The plasma does not generate a coherent magnetic field. It requires a current driven in the plasma to generate the magnetic field. It would require massive currents to produce fields you mention.
