Yuri Andrade Sylvester [email protected] October 2, 2004 ENGRI 111 Homework #4 Due Monday, October 4, 2004 1. Write concise answers for the following questions regarding magnetic moments: a. What are the two sources of magnetic moments for electrons? Why? The two sources for magnetic moments in electrons are spin momentum and orbital momentum. The electron is analogous to a small current loop that generates a small magnetic field, and which has a magnetic moment along its axis of rotation. Also, each electron can be thought of as spinning around an axis. The magnetic momentum that is originated as a consequence of this is directed along the spin axis (this can have a value of +1/2 or -1/2). b. Do all electrons have a net magnetic moment? Why or why not? No, because electrons can be thought of as being a small magnet having permanent orbital and spin magnetic moments. This is a partial constituent of the atom, and therefore it is has a partial (not net) contribution to the magnetic moment. Plus, net means that there is
