I consider the same operator as in part I assuming however that $\mu \ge Ch^{-1}$ and $V$ is replaced by $(2l+1)\mu h F+W$ with $l\in \bZ^+$. Under some non-degeneracy conditions I recover remainder estimates up to $O \bigl(\mu^{-{\frac 1 \nu}}h^{-1} +1\bigr)$ but now case $\mu \ge Ch^{-\nu}$ is no more forbidden and the principal part is of magnitude $\mu h^{-1}$.
