A Gaussmeter, also known as a magnetometer, measures magnetic field strength using specialized sensors. The most common type employs the Hall effect principle. Here's how it works: A thin semiconductor material (Hall sensor) is exposed to the magnetic field being measured. When electric current flows through this material, the magnetic field exerts force on the electrons, creating a measurable voltage perpendicular to both the current and field direction. This voltage, called the Hall voltage, is proportional to the magnetic flux density.

Another type uses fluxgate sensors containing high-permeability cores wrapped with coils. An alternating current saturates the core cyclically. External magnetic fields alter the core's saturation pattern, inducing detectable secondary voltage changes in pickup coils. Sophisticated electronics then process these signals, converting them into precise magnetic field readings displayed in units of gauss or tesla.
