Electromagnet Bell Demonstration, 3-6V AC Included_Rod & Base & Clamps Bare 20 SWG copper wire

Bare 20 SWG copper wire on a 250g reel approximating 140 feet

Air-cooled rheostat at 36 ohms and 3A with constantan winding on a 300x44mm vitreous-enameled tube

providing the more readily oxidized electrode that drives current in classic galvanic-cell demonstrations

sized to drop different loads into a circuit without rewiring

showing the deflection of a current-carrying wire through a fixed magnetic field via 4mm safety sockets

Electromagnet Bell Demonstration, 3-6V AC Included_Rod & Base & Clamps Bare 20 SWG copper wireOpen mount electromagnet bell on an 8x4 inch wooden base with a push button and 4mm banana sockets, exposing every wire and hammer so students trace the bell's electromagnetic action.
