A three-axis magnetometer measures magnetic-field components along three sensor axes. A device may use different magnetic transduction technologies, including Hall-effect implementations; the specified sensing principle depends on the product. Field readings can support heading, proximity or magnetic-state analysis, but are not inherently a complete compass or distance measurement.
