Magnaprobe
Demo Description
A tiny bar magnet is gymballed so that it can rotate in 3-D.
One can bring this near various configurations of magnets to investigate the local magnetic field.
Scientific Principles
Magnetic field; Magnetic lines of forceEquipment
- Magnaprobe
- Magnets
Equipment Location
- The magnaprobe is in [B-2-6]
- Magnets are in [A-2-1]
Instructions
The figure shows the magnaprobe detecting the magnetic field of a neodynium magnet.
Move the magnaprobe around near any configuration of magnets to help students visualize the magnetic field in 3D.
