F= k* q1*q1/r^2There 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 thing.
How do you call the place in a magnetic field towards which opposite magnetic field gets attracted to? Why is that not a sink?Um, I suppose you could wave a Hall probe around in space. I don't think it's very meaningful to point to something and call it a magnetic pole in the same sense as you could with one half of an electric dipole, precisely because there are no sources/sinks. I guess this probably renders the electron thing moot too.
How do you define "pole"? How do you define "sink/source"?Some people have built particle detectors to search for magnetic monopole "rays", pull monopoles out of meteor dust (and moon dust?), and even built the magnetic equivalent of a toroidal electric circulating current, using ground-up meteor dust in balls of epoxy. No monopoles found.
