Sun Spot Activity When the sun produces huge quantities of charged particles and sends them out into space, the action is known as sun spot activity. When that happens, the strength of the current in the radiation belts increases and so does the strength of the magnetic field. In some instances, the magnetic field becomes so strong that it causes what is known as magnetic storms that affect navigation and electrical activities on Earth. Magnetic storms cause power outages and interfere with navigational instruments and other types of sensitive electronic equipment.
