WebIn answering the question "Why do "Electrons Move", you say "With a strong enough force, it is possible to give an electron enough energy to knock it up to a higher energy orbital, or even completely off of the atom (if the force which is giving it the energy to move around is stronger than the electric force holding it near the nucleus). WebA proton's magnetic moment arises from a fundamental quantum property called spin, which causes the proton to behave as a tiny bar magnet with a north and a south pole. When placed in an external magnetic field, the proton's spin can either align with the field or flip to orient itself against the field.
