Hall

Magnetic measurement for dummies

Advantages

Nearly instantaneous

Sensitivity can be adapted for wide range of medium- and high-field applications

Readily integrated into electronic system

Measures a single vector component of field (almost)

Constraints

Precision less than NMR or fluxmeter techniques

Careful calibration required to compensate for voltage offset, temperature dependence and non-linearities

Periodic recalibration required to compensate for drift

Angular dependence introduces hard-to-control measurement error
