Higher quality (and typically more expensive) stainless steel appliances will not hold your alphabet magnet set. Do electron , muon, tao, electron neutrino, muon neutrino and Tao neutrino share a same origin at the beginning. Magnetizing this ferromagnetic object means making its magnetic moments point in the same direction. There is usually an adhesive on one side that allows you to stick the tape to an item which will then allow you to stick that item to something like your refrigerator. In other words, electrons orbit around the atom nucleus, and this movement of electrons is alike moving electrons (moving charge) in a conductor. If they're all oriented, we call this "saturation" -- it cannot be magnetized further by applying external field. There are other sources of magnetism in an atom, such as magnetic moments of the nuclei, but these are very small in comparison. Issuu company logo.
