Field lines in TOKAMAK

[Numeriprimi]

How look field lines in TOKAMAK? Do you have any picture? How I could physically make for a better understanding? (of paper, laser, ...)

Did you try to do a search on this? I did a google search on your phrase "field lines in TOKAMAK" and got a slew of hits, including one at ORNL

Were you having problems finding such things?

I searched for it on the Czech internet and I didn't found some suitable. When I searching in English, I'm not too sure if I found the correct content.
Thank you.

Keep in mind that the field lines change drastically inside the reactor when you heat the plasma up and introduce current through it. I've got a book on Principles of Fusion Power and there are numerous issues with the field lines getting all mucked up inside the plasma, leading to instabilities and such. It's one of the main challenges with magnetic confinement methods.
