- Device for measuring magnitude of magnetic field around current conducting wire.
- Placement of two compasses demonstrates the magnitude of a magnetic field as a function of distance from a conducting wire.
- Demonstrates direction of magnetic field as dependent upon direction of current and position of compass
- Easy to read the data on the compass
- Includes two Compasses of 10 cm diameter (1 Deg resolution)
