Will magnetic fields influence plasma ball discharges?

[rakave]

Plasma balls discharge charges of light. Light can be influenced

by magnetic fields. Could they be compacted by magnetic fields enough to be able to cut matter. Something like a laser but with a controllable length.

Sounds a lot like a lightsaber to me

 

Unfortunately, I don't think that's how it works, but I don't really know for sure.

Since when was light affected by magnets other than the fact that the magnet's mass curves space-time and the photons follows that curvature (aka gravity)?

 

And what do you mean by plasma balls?

I've done reactive-ion-etching on nanoscale materials. The width was controlled by a mask made from a resist material (PMMA). I suppose you could control the depth by timing the discharge, but I don't know how well that could be conntrolled. All of this done in a vacuum system.

 

So a plasma can cut through materials, under the right conditions.

 

Light, however, is not directly affected by magnetic fields.

A plasm, by definition, is cloud of positive and negative ions, and as such they are influenced by a magnetic fields.

 

Fusion reactors, like the tokamak design, use a magnetic bottle to contain the ultra-hot plasma, that would otherwise be bad for the surfaces of the reactor.

 

Google turned up this links. Look them over.

it controls the electron flow, the light given off is just an extra due to its excitation, it`s the electrons it influences, a bit like the magnetic coils in the back of a TV used to focus and move the electon beam.
