Hall Effect Magnetic Field Measurement Apparatus Sale and automatically powers off toMeasure magnetic field strength with precision and ease The Hall Effect Probe is a classroom sensor designed to measure magnetic field strength directly. It allows students to quantify magnetic flux density (B) in real time using the Hall effect, where voltage is proportional to the applied magnetic field. With a measurement range spanning from very weak fieldssuch as Earths magnetic fieldto strong permanent magnets, the probe supports a wide variety
