The motor of a fan works because of electromagnets, and electromagnets do work in vaccum so the fan will also work in vaccum.But, the fan will not cause any flow of anything because there is nothing to flow.
yes. to make it stronger, increase the electric flow.
As soon as the flow of electrical current ceases, the magnetic field collapses [or "turns off"].

You can turn electromagnets on and off.
Yes, electromagnets itself is an artificial magnet.
