  • Affordable – a fraction of the price of the ‘big name’ brands.
  • Simple interface – very easy to use.
  • Configurable – range (+/- 4G, 8G, 12G or 16G), units (gauss, milliTesla, microTesla), axis (x, y or z axis).
  • Includes “Tare” and “Calibration” features.
  • Designed and assembled by a Physics teacher (formerly electrical engineer) in Brisbane, Australia.
  • Available for Windows only at this stage (sorry Mac and Linux users!)

What you get:

  • A Magnetic Field Sensor (6 of them if you order the class set)
  • A 1.5m USB cable
  • Driver and software are free downloads from our Setup and Use page

Possible Student Experiment Ideas

  • Investigate the relationship between the magnetic feild strength in a solenoid, and the current through the solenoid. (This is a “suggested” experiment in the QCAA syllabus).
  • Investigate the relationship between the magnetic field strength at various distances away from a current carrying conductor.
  • Investigate the relationship between the magnetic field strength in a solenoid, and the turns density of a solenoid (using a slinky as the solenoid).
  • Investigate the magnetic field strength along the axis of a current carrying multi-turn loop.
  • Investigate the magnetic field strength between the centre and the perimeter for a current carrying loop.
  • Investigate the magnetic field strength along the axis of a Helmholtz coil.
  • Investigate the magnetic field strength between the centre and the perimeter of a Helmholtz coil.
  • Investigate the relationship between the magnetic field strength and the distance from a bar magnet.
  • Investigate the magnetic field outside of a solenoid.

What Teachers are Saying

“I just wanted to pass on my sincere thanks and appreciation for your magnetic field sensors. We collected data for IA2 this morning and I have never had such a smooth process and this was in no small part thanks to how easy your sensors are set up and collect data with.”

“This year we bought some of your magnetic field sensors. Thanks for creating these – they are a great improvement on the <big name brand> sensors that we have been relying on in the past (and much cheaper). … The sensors are very easy to use, and the kids found them reliable, giving good steady data.”

“The ‘gizmos’ are excellent. So easy to setup and worked first time! I will be looking forward to the experiments that the students come up with later this term. Thanks again for making such a useful piece of kit at such a good price. I’m sure you could charge double and still have happy customers!”
