Web13 de jun. de 2016 · Basically, every time you have a moving charge you have the formation of a magnetic field; for example: 1) around a wire carrying electricity; 2) in a magnetic material; this time caused by the electrons "moving" around in the atoms; 3) in and around a solenoid carrying a current (as in a transformer). Hope it helps! Answer link WebThe electrons have an electrical charge, so when they orbit they form small loops of electrical current around each nucleus. Magnetic fields are formed by electricity. In most materials the little magnets formed by each atom are all pointing in different directions, and so they cancel each other out. In some materials such as lodestone, an iron ...
