Electromagnet Bell Demonstration, 3-6V AC Included_Rod & Base & Clamps Air-cooled rheostat at 36 ohms

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

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

sized for side-by-side strength comparison against the chrome-steel cylindrical series of similar dimensions

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 Air-cooled rheostat at 36 ohmsOpen 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.
