Measuring magnetism

With a gauss meter - also called tesla meter or magnetometer - you measure locally - on the surface - the magnetic flux density in units of tesla, gauss, Ka/m or oersted. Flux density is a measure of the amount of magnetic flux through a surface. Goudsmit also conducts magnetic measurements on site if desired.

Gauss meter measurements use the Hall effect as the measuring principle. The sensor captures the magnetic flux density that is perpendicular to the sensor plane. The magnetic field generates an output voltage on the sensor, which is proportional to the product of the magnetic field strength and the induced current.

There are two types of gauss meters:

• 1D - for measurement on a surface
• 3D - for measurement of magnetic fields in a free space
