A compass can be moved to show the field direction, and field lines are drawn through the position of the magnet. Material is available in 13 languages. http://www.merlot.org/merlot/viewMaterial.htm?id=76439 This is an illustration of the circular magnetic fields around a straight current-carrying wire. Current flow (of electrons) is indicated in the wire. The magnetic field direction is illustrated by arrows on the magnetic field lines and a magnetic compass that can be moved on a plane perpendicular to the current. Material is available in several different languages. http://www.merlot.org/merlot/viewMaterial.htm?id=80259 A set of four archival recordings from the University of Auckland (New Zealand) of the physicist Richard Feynman. The lectures focus on the quantum nature of light and Quantum Electrodynamics.
