The movement or spinning of the electrons (subatomic particle) creates magnetism.
Answer: electrons
Explanation:
Magnetism occurs due to the motion of electric charge. Each atom contains electron, particles which possess electric charges. The electrons rotate like spikes and revolve around the atomic nucleus.
Their movement produces electric current and ensures that each electron acts like microscopic magnets. Therefore, magnetism is observed when electrically charged particle move.
For example, by moving of electrons in an electric current or, in some cases, the movement of orbital electrons around the atomic nucleus.
