Lorentz force turning
Lorentz force turning is an innovative technique proposed for steering interstellar spacecraft (see interstellar probes and interstellar propulsion). It would involve unreeling several extremely long space tethers and giving them a high electric charge. The Lorentz force (a force experienced by a charge moving in a magnetic field) between with these tethers and the galactic magnetic field would result in the spacecraft undergoing a slow, constant course change which, over time, would be enough to switch the trajectory from one star to another.
