Some physicists from the University of Alberta have discovered the reason answer to why changes to Earth's magnetic field over time are weaker over the Pacific region. According to geophysicist Mathieu Dumberry, there are fluid motions in the liquid core of the Earth that generate and maintain the Earth's magnetic field, which gives us the Northern Lights and shields us from charged particles from space.
