How can we contain something that gets as hot as 100M Celsius? And how can we measure it?

Question

I have been reading articles describing the progress made towards fusion energy and got intrigued by how they do it.

Answer 1

Fusion will be like a jet engine. Jet engines take power from the fire and use most of it to keep the engine going. Then the left over power pushes the airplane. The fire and hot gases would melt the engine if they touched the little spinning wings inside. careful design and engine power keeps the engine from getting too hot.

Fusion generators will use most of the electricity they make to keep the fusion engine safe. Strong magnets will keep the tiny little ribbon of heat in the middle of a box while other machines take the heat away to make electricity. I wonder if they might even spin like a jet engine.
