Changing particle spin

  1. Mar 25, 2013 #1
    Okay, so I was looking at some ideas of storage based on making electrons spin "up" or "down" to store binary data, and I began wondering two things:
    1) How does one change the spin "orientation" (for lack of a better word) of a particle?
    2) How does one detect the spin "orientation" of a particle?

    Thanks in advance for your help.

    With magnetic fields of the right direction and intensity.
    With their interaction with magnetic fields, or maybe other clever ways (like processes possible for one spin orientation only).
