How is magnetic flux different from magnetic field? Or rather how are they related to each other ? My thought is say there is a magnetic field acting along the x-axis direction, a conductor is allowed to fall through the magnectic field and now there is a change in magnetic field, hence magnetic flux is produced ? Is is sth like that? And also whats eddy current? Is it the current induced when there is a change in magnetic flux and eddy current is simply the special name for it ?
