WebAug 3, 2024 · Earth’s magnetic field acts like a protective shield around the planet, repelling and trapping charged particles from the Sun. But over South America and the southern Atlantic Ocean, an unusually weak spot in the field – called the South Atlantic Anomaly, or SAA – allows these particles to dip closer to the surface than normal. WebSep 5, 2024 · The two sources of magnetism are electric current and spin magnetic moments of elementary particles (primarily electrons). A strong magnetic field is produced when the electron magnetic moments of a material are aligned. When they are disordered, the material is neither strongly attracted nor repelled by a magnetic field. What Is a Magnet? WebNov 11, 2024 · The second explanation is that the current carrying wire induced a magnetic field, this field interacts with the external field to form repelling or attracting forces. This is the "field-only" approach. The electromagnetic field stores energy with density. U = 1 2 ( ϵ 0 E 2 + 1 μ 0 B 2). In general this means that the total energy of an ... foam and cement
