The Magnaprobe™ magnetic field indicator is a small bar magnet fully suspended in a gimbal mounting and is designed to show the three dimensional nature of a magnetic field. The Mark I model is more sensitive than the Mark II, being mounted on precision bearings and balanced to show the dip of the Earth's magnetic field.
It can be used to show the three dimensional nature of the following:
- Forces between magnetic poles
- Induced magnetism
- The shapes of magnetic fields between like and unlike poles
- Direction of a magnetic field around a bar magnet, a wire or a coil
- Properties of a field produced by an electric current.
- The direction and dip of the Earth's magnetic field
