A handheld field meter reading the device magnetometer on a five-lamp scale, with a CRT-style readout, needle movement modelled as a spring-mass-damper, and a session log of what was measured.

Where no magnetometer is exposed - which is most desktop browsers - it says so plainly and runs a labelled simulation. A changing reading indicates a change in the local magnetic field near the device, and nothing more than that.

This is an instrument and a sound tool, provided for entertainment and experiment. It describes what it measures and does not identify the cause of anything it shows.
