... Or in other words in that case the sources of the magnetic H-field are equal to those area that have a non-zero divergence. Note that the divergence is zero in a homogeneously magnetized object. Also note that the divergence is unequal to zero if the normal component of M has a non-zero component. C ...

... 1. Recall that the angular momentum raising operator is L+ = ~eiφ (∂θ + i cot θ ∂φ ). Use this to find L− . 2. Use the above formulae for L± to find the coordinate representation of the angular momentum basis states Y11 , Y10 and Y1,−1 up to normalization. 3. Write out the 9 equations summarized in ...
