Magnaprobe with Magnetic Globe, 1 Each

The Magnaprobe with Magnetic Globe by United Scientific is a demonstration set that models the Earth's magnetic field using a 110 mm detailed globe with a magnet along its axis and a magnaprobe whose magnet rotates on two axes. Students trace the field direction across the surface and see the field angle steepen toward the poles. Earth science and physics teachers use it with the included activity guide on geomagnetism, the Van Allen belts and the northern lights.
