Web2 aug. 2024 · So far my understanding of a permanent magnet is: Since elements like iron have atoms with orbitals that have many electrons with the same spin, these cause the metal to have a magnetic field, which exerts a magnetic force on moving charges, I would like to know if my understanding is correct or what is the correct explanation for … Web2 apr. 2007 · Magnets are objects that produce magnetic fields and attract metals like iron, nickel and cobalt. The magnetic field's lines of force exit the magnet from its north pole …
WebThe strongest permanent magnets are made from an iron-neodymium-boron (Fe-Nd-B) alloy. This kind is actually used as a critical part of a nuclear physics experiment called the Alpha Magnetic Spectrometer (AMS). Almost without exception, nuclear physics experiments require a strong magnet and it is often a superconducting one. Web1 apr. 2024 · magnetic field, a vector field in the neighbourhood of a magnet, electric current, or changing electric field, in which magnetic forces are observable.
