When we think of cosmic power, magnetism doesn't usually come to mind. The Sun's nuclear furnace churns out blistering heat and blinding light, but magnetism plays no role in the fusion process, which converts our star's mass to energy. So a star's magnetic field is like cole slaw: nice but unnecessary. Certainly irrelevant in the energy big leagues. At least, that's how it always seemed.
