Abstract
This paper describes a demonstration where a micromechanical Lorentz force magnetometer is used for measurement of 50 Hz active power. The magnetometer reacts to the external current and voltage, where current coupling is magnetic and voltage coupling is galvanic. The output is proportional to their product. Even though the component used for this demonstration is not optimal for the purpose, a clear response to active power was obtained.
