@ 01:58 Of course, spin has a classical analogue, but no analogue is perfect. The spin of a top, or the spin of the Earth are examples. A difference is that classical spin is continuous (= not quantized). @ 19:50 This result shows that there is no component in the z-direction. So where is in MRI the magnetization-vector coming from? By the way, it is SPIN or INTRINSIC ANGULAR MOMENTUM; but not spin angular momentum.
