The spin of an electron is designated by ms, the electron spin quantum number, which can have values of +1/2 and -1/2.In the presence of an external magnetic field an electron in an orbital can have one of two possible energy states, which depend on whether the magnetic field associated with the electron is aligned with or against the external magnetic field.
Classically, the magnetic property of the electron derived from its nature as a "spinning" negative charge analogous to a current flowing in a "ring". Thus, electron may be viewed as a bar magnet with its north pole oriented either "up" or "down".
Spin is an industrial metal band from the Maltese Islands. The band was originally formed by Martin Ciappara and Simon Deguara in 1999 who released the first demo CD named Pead. The style started taking a more electronic and industrial form later on, with Eric Mangion joining in on samples, Richard Gatt on bass, and Josef Bajada on guitars.
