WebThe International System of Units (SI) unit of magnetic field intensity, strictly flux density, most commonly used in geomagnetism is the Tesla. At the Earth's surface the total intensity varies from 22,000 nanotesla (nT) … WebThe strength of the magnetic field is strongest near the poles and weakest near the equator. The Earth's magnetic field intensity is roughly between 25,000 - 65,000 nT. The parameters describing the direction of the magnetic field are declination (D) and inclination (I). Magnetic declination is the angle between magnetic north and true north.

A Van Allen radiation belt is a zone of energetic charged particles, most of which originate from the solar wind, that are captured by and held around a planet by that planet's magnetosphere. Earth has two such belts, and sometimes others may be temporarily created. The belts are named after James Van Allen, who is credited with their discovery.
