You mean if I have a conductor (plasma) and pulse a magnetic field (the curl of current) with no potential present, no charges will be put in motion, and no pondermotive force will be experienced? You really sure about that?

Isn't the magentic field also included?

In superconductors

Your reasoning:
You must have a potential for a current to exist
current is proportional to potential
more potential more energy

My reasoning:
Energy and force are mediated by electric AND magnetic fields
Charges in motion have a current
Charges have a current they magnetic moment
Magnetic fields accelerate magnetic moments
No potential needed, in fact a potential is an indicator of resistance or energy loss. The less potential the better for magnetic acceleration

When Hundreds or thousands of volts are dropped across a few milli-ohm plasma, the current would be >10 KA.
