the wider-range Wheatstone-bridge reference

used to demonstrate capacitance and the discharge of stored static charge

sized for whole-class visibility of momentum-and-energy conservation through pendulum collisions

Exposes every moving part of a two-pole armature rotating between permanent magnets on an open 4-inch plastic base

Open-base DC motor-generator activity model with a 2-pole enameled copper armature

Simple Electromagnetic Demonstration Motor Subcategory_Lab Burner Accessories the wider-range Wheatstone-bridge referenceOpen frame demo motor with two opposing coils on a spinning axle and 4mm banana inputs, exposing the moving parts so students see directly how a DC current drives a rotating magnetic field.
