Tangent Galvanometer

Classic demonstration of how a current loop generates a magnetic field.  Two coils of insulated wire, with 5 and 10 turns respectively, are wound around a 6" diameter plastic ring.  The ring is mounted on a plastic base with 3 binding posts that allow connection to five, ten, or fifteen turns of wire. A magnetic compass (included) can be placed on the base to observe and measure deflection of the compass.  An activity guide is included.  Power source and connecting wires not included.
