Magnetic confinement fusion

Lockheed Martin Pursuing Compact Nuclear Fusion Reactor Concept
The top of this image shows how early in the heating, magnetic fields, drawn as black lines, prevent heat from flowing easily between the two yellow laser spots. Later in the heating, as depicted on the bottom half, the moving magnetic fields continually connect and provide a channel for heat to flow between the two laser spots. This newly discovered magnetic behavior could advance nuclear fusion. Image credit: Joglekar, Thomas, Fox and Bhattacharjee
