Magnetic Measuring Instruments

Magnetic measuring instruments are devices used to detect, quantify, and analyse magnetic fields, magnetic flux, residual magnetism, or the magnetic properties of materials.

Core Types of Magnetic Measuring Instruments

• Magnetometers: Instruments designed to measure magnetic field strength, direction, or dipole moments. They are split into scalar/total field meters and vector magnetometers (measuring fields in specific directions). Examples include fluxgate, proton precession, optically pumped, and SQUID magnetometers.
• Gaussmeters and Teslameters: Devices that measure high magnetic field strengths (typically above 1 milliTesla) or residual magnetism on component surfaces. They frequently use Hall-effect probes to sense fields in tight air gaps or around permanent magnets.
• Vibrating Sample Magnetometers (VSM) & Lab Balances: Laboratory systems used to characterise materials’ bulk magnetic properties, hysteresis loops, and magnetisation curves under static or varying magnetic fields.
• Magnetic Flow Meters (Magmeters): Industrial flow measurement tools that use Faraday’s law of electromagnetic induction to calculate the velocity of conductive liquids passing through a magnetic field without internal moving parts.
• Magnetic Field Viewers: Special films or liquid solutions that visually map out weak residual magnetism, pole patterns, and magnetic flux lines on flat metallic surfaces.
