What is paleomagnetism? Why have magnetometers shown symmetrical bands of magnetism strength at varying locations?
· Paleomagnetism is the study of fossil magnetic fields. It uses the magnetite in magma to determine the direction of the magnetic field and even the orientation of the continents at various times in history.
· Paleomagnetism can show the alterations between weak and strong bands of magnetism. This suggests the orientation of the magnetic pole has shifted numerous times.
· Magnetometers measure the amount and direction of residual magnetic fields.
· Some bands add to Earth's present magnetism while others have weakened it.
