Main Question or Discussion Point

this question might be a bit stupid, but if the plasma in the fusion reactor has very high temperature, then how do we make the chamber not melt? i mean, not to join? contact? each other(chamber wall and plasma).
do we use magnetic field to make the distance? then how do we do that?

There is at least one other approach which is not entirely reliant on magnetic confinement, although that is still a part of the story.

This statement is very misleading. It is true that there are alternatives to magnetic confinement.
However, stellarators like Wendelstein rely entirely of magnetic confinement.

OK thanks for that correction, I had thought that the stellarator project used a combination of containment methods, with magnetism being one, but didn't have time to recheck on that.

Both tokamak and stellarator use magnetic fields only. Just the origin of the field is different: Tokamaks need a magnetic field component that has to come from a plasma current (together with the stronger fields from coils), stellarators work with magnetic fields from coils only.
