Geomagnetic changes can be used to deposit exploration.

if with the current conductor in a rotary magnets, like the force, so that these particles Arctic southward movement and aggregation, and high-altitude thin gas and Earth collide, resulting gases excited molecules to emit light. Sunspots are very intense magnetic activity on the sun's area. The outbreak of sunspots on our lives will have an impact, such as making radio communication temporary interruption.neodymium block magnet, the study of sunspots is important to us.
