Demonstrate the relationship between electric current and magnetic fields.
- Used to demonstrate how a current loop generates a magnetic field
- Magnetic compass and activity guide included
- Power source and connecting wires not included
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.
