Not a homework question! Consider a proton and coordinate system immersed in an upward pointing external B-field. If the orbital magnetic number m (sub l) is a positive hbar then the vector precesses counter-clockwise about the positive z axis. 1. If m (sub l) is a negative hbar then does the vector precess clockwise around the negative z-axis? 2. What about when m (sub l) has a vector length of sqrt 6 and a 0 hbar orientation. Which direction does the vector precess?
