Earth's magnetic field switching
WebAug 3, 2024 · Since the forces that generate our magnetic field are constantly changing, the field itself is also in continual flux, its strength waxing and waning over time. This … WebMagnets can occur naturally (such as the Earth’s magnetic field), or they can be made by magnetizing ferromagnetic materials. Magnetic fields ultimately are the result of the motion of charges. A typical representation of this can be seen in the figure below.
