Spinning electrons Electrons have a property called spin. This spinning creates a magnetic field with N and S poles, just as the spinning Earth has magnetic poles. Note that the N pole on an electron is really a North-seeking pole, just as in a magnet. If electrons in the shells of an atom spin in the same direction, the atom will exhibit a magnetic field and will respond to the forces of a magnet. If half of the electrons spin one way and the rest spin the other way, they will neutralize each other and the material will not be affected by a magnetic field This atom is barely magnetic because all its electrons are not aligned http://www.school-for-champions.com/science/magnetic_factors.htm Magnetic fields can change the direction of spins by inducing "precession" which is an additional rotation of the spin orientation about the magnetic field, similar to the periodic movement of the axis of a top after it is spun. While the speed of electron spin precession in a magnetic field is generally fixed by the particular materials used, the research reported in Nature has shown that both the speed and direction of precession can be continuously adjusted by applying electric fields in specially engineered quantum structures.
