YouTuber Proto G shot these cool experiments with plasma vortex force fields. Scientists are looking into large-scale practical applications of the force field generated in this manner:
This video demonstrates how a magnetic field affects the charged particles in a plasma arc. Plasma actually does make a functional force field. A University of Washington group in Seattle has been experimenting with using a bubble of charged plasma, contained by a fine mesh of superconducting wire, to surround a spacecraft. This would protect the spacecraft from interstellar radiation and some particles without needing physical shielding.
Here’s some more science behind the device:
