Undergrad What is magnetic pole? What is sink/source?
There are monopoles and there are dipoles. Monopoles are sinks/sources (e.g. point masses, charges) which give a nonzero divergence. Magnetic dipoles (the type you find in solenoids, say) give zero divergence because on the whole they are neither sources nor sinks. So no, they are not the same...- darthoctopus
