Earth's magnetic field switching
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. WebSep 27, 2004 · Scientists believe Earth's magnetic field is generated deep inside our planet. There, the heat of the Earth's solid inner core churns a liquid outer core composed of iron and nickel. The...

WebJul 6, 2024 · Earth's magnetic north and south poles switch at irregular intervals at an average of every 200,000 years or so, and the event could have a dramatic effect on the environment and technology.
Through analysis of seafloor magnetic anomalies and dating of reversal sequences on land, paleomagnetists have been developing a Geomagnetic Polarity Time Scale (GPTS). The current time scale contains 184 polarity intervals in the last 83 million years (and therefore 183 reversals). The rate of reversals in the Earth's magnetic field has varied widely over time. 72 million years ago (Ma), the field reversed 5 times in a million years.
