Magnetic field of sphere
WebMagnet spheres spin fast next to each other due to the magnetic fields that they each give off. Since opposites attract in magnetism, the opposite poles will make them move closer together, while the same poles will repel them away. Since spheres have around and smooth surface all around, they are able to rotate and orient themselves according ... http://www.usrareearthmagnets.com/poles-of-spherical-magnets/

Web22 jul. 2010 · The lithospheric contribution to the Earth’s magnetic field is concealed in magnetic field data that have now been measured over several decades from ground to satellite altitudes. The lithospheric field results from the superposition of induced and remanent magnetisations. Web3 aug. 2024 · Earth is surrounded by a system of magnetic fields, called the magnetosphere. The magnetosphere shields our home planet from harmful solar and cosmic particle radiation, but it can change shape in response to incoming space weather from the Sun.

In fact, . It is clear from Figure 4 that for a magnetic material to be a good permanent magnet it must possess …
Webdipole fields that vary appreciably on the atomic scale. The process of averaging the microscopic quantities to obtain the macroscopic description on magnetic fields in matter will be discussed in the second part of EM. The result of this averaging is a macroscopic magnetic field B which obeys the same equation B 0 (6.1)
