Step 0 (not shown): An axial magnetic field (around 30 T) is applied to the fuel.

Step 1: A laser (around 3 kJ) preheats the fuel, ionizing it.

Step 2: A large current (around 30 MA) is driven through the liner.

Step 3: The current induces a strong azimuthal magnetic field.

Step 4: The magnetic force on the liner pushes it inward, compressing and heating the fuel to fusion-relevant densities and temperatures. The initial axial magnetic field is also amplified. Fusion reactions ensue in the fuel, releasing energy.

Step 5 (not shown): The imploded liner and fuel column falls apart and disperses into the target chamber.
