Does an electron really spin about its own axis? If not, what does spin magnetic moment imply? My physics teacher said "Besides the orbital moment, an electron has an intrinsic magnetic moment, it is called the spin magnetic moment, But I hasten to add that it is not as though the electron is spinning." But, in my chemistry textbook, there's an illustration of an electron apparently "spinning" about its own axis. Moreover, the direction of spinning has also been shown.
