Problem

Verify explicitly that the magnetic monopole is rotation invariant in spite of appearances. By this is meant that all physical gauge invariant quantities such as

\vec{B}

are covariant under rotation. Gauge variant quantities such as

A_i^b

can and do vary under rotation. Write down the generators of rotation.
