‘The Earth has a magnetic field, and so do the Moon, the Sun, the other planets, and the galaxy itself. The Sun’s magnetic field extends far out beyond the planets, creating a plasma shield around the solar system that protects it from external intrusions, like the membrane of a cell protecting the cell. So here on the Earth we are very much under the influence of the Sun’s magnetic field as well as the Earth’s.
Similarly, the magnetic field of the galaxy extends beyond the visible galaxy, creating a plasma shield around the galaxy. So we are very much under the influence of the galaxy’s magnetic field as well. The Moon’s magnetic field is not very strong, but because the Moon is so close, we are also influenced to some extent by its magnetic field.
Thus, the magnetic fields of the Earth, Moon, Sun, and galaxy all influence the magnetic energy fields we are experiencing at any given time. As to why that’s important we will get to later. For now I just want to make it clear that all four influences are significant, as regards the magnetic field being experienced on Earth.’
