Scientific experiments in which high temperatures are applied to magnets indicate that their magnetism is totally destroyed on reaching what's known as the Curie Temperature (310 degrees C.). Since the Sun's temperature is said to range from thousands to millions of degrees (well above 310 degrees, to put it mildly), this means that it could have absolutely no magnetism whatsoever, and therefore no rays in the electromagnetic spectrum could be radiated by the Sun to the solar system planets. The idea that our solar orb is a furnace of millions of degrees heat is in direct conflict with the fact that electromagnetic energy is emitted by it.
