Abstract
Angular momentum and rotation are related in several complementary
ways. Rotating material systems contain angular momentum, and the
quantum-mechanical operators for angular momentum are the generators
of rotation. In mechanical systems, we naturally distinguish spin
and orbital angular momentum as intrinsic and extrinsic
contributions. For Maxwell fields, the situation is less
straighforward. We shall analyze the analogues of these statements
for electromagnetic fields in general, and for light beams in
particular.
