Thank you for that thorow answers.

As I know it could be easier to transfer electrical energy from a broad contact area and short distance to the plasma or easier to achieve high current. If you then can keep the voltage as high as before, then short distance is good for transfer more heat.

When it comes to the magnetic field I’m more puzzled. Physics law says B = n*I*k, k is a konstant around 2*10(raised-7) in vacuum and air etc, n number of laps, because the plasma wind up like coil. That would mean that a greater distance gives higher magnetic field, since there are room for more laps in the longer coil.

A stronger magnetic field means a denser plasmoid, but how about time? Does the strength of the magnetic field affect the time the plasmoid exist? Longer time is also favorable. But I don’t have a clue if and what connection there is between time of the plasmoid and the strength of the magnetic field. Some who knows? Could there be a optimal value for the strength of the magnetic field.

To me it seems as the magnetic field gets what it gets? If size and current is decided to reach high temperatures, then there is not much room to affect the magnetic field itself.
