An Oscillating Magnet Watt Balance

2016    Ahmadov, Haji

We establish the principles for a new generation of watt balances in which an oscillating magnet generates Faraday's voltage in a stationary coil. A force measuring system and a mechanism providing vertical movements of the magnet are completely independent in an oscillating magnet watt balance. This remarkable feature allows to establish the link between the Planck constant and a macroscopic mass by a one single experiment. We formulate the oscillating-magnet watt balance principle and establish the measurement procedure for the Planck constant. We discuss the nature of uncertainties and give a brief description of the apparatus.
