Solar radio bursts reveal hidden magnetic switchbacks near the sun, Parker Solar Probe data suggest

Solar radio bursts are intrinsically linked to the motion of their emitting source through the coronal and heliospheric plasma. Electron transport is mostly confined to magnetic field lines. These electrons move at a substantial fraction of the speed of light and often generate radio emission via the plasma emission process.
