WebElectromagnetic induction can create a voltage by movement of a conductor in a magnetic field. This voltage can make current flow, and the effect is used in electricity … Web13 de dez. de 2024 · Magnets and electricity. Basics. The spinning of the electrons around the nucleus of an atom creates a tiny magnetic field. The electrons in most objects spin in random directions, and their magnetic forces cancel each other out. Magnets are different because the molecules in magnets are arranged so that their electrons spin in the same …
