At the thermonuclear fusion temperature of 100,000,000 kelvins the hot plasma could easily vaporize its own material container. Therefore, the container must be shaped by an enclosing nonuniform high intensity magnetic field. Such that it is the magnetic field which come in contact with the hot plasma and not the surface of the material container. This device is known as a magnetic bottle and is based on the same principle of magnetic containment as that which shaped the spherical magnetic configuration of the sun and all stellar systems.

However, there remains a crucial distinction between man-made and natural stellar bottles. This is the phenomenon of magnetic helicity. The engineering of man-made stable nondissipative magnetic helicity does not exist at this time. On the other hand, the magnetic helicity of the sun is still not completely understood. Furthermore, no man-made magnetic bottles was able to sustain hot plasma long enough to initiate thermonuclear fusion. This deficiency again could be due to the lack of dynamic equilibrium of weak magnetic helicity that arise in the container caused by nonzero electric resistivity and magnetic reconnections in current sheets.
