MAGNETIC ELEMENTS THAT DETERMINE THE EARTH’S MAGNETIC FIELD AT A POINT
The magnetic elements that determine the Earth’s magnetic field at a point are: 1) Magnetic Dipole Moment: The Earth can be approximated as a magnetic dipole, with a magnetic north pole near the geographic south pole and a magnetic south…
MAGNETIC MATERIALS EXPLAINED
Introduction Magnetic materials are materials that can be magnetized to produce a magnetic field. The ability of a material to become magnetized depends on its atomic and molecular structure, and on the presence of magnetic dipoles or spins in the…
