  The UME Kibble balance project was initiated at the second half of 2014.
During this period we have studied the theoretical aspects of Kibble balances
in which an oscillating magnet generates AC Faraday voltage in a stationary
coil and constructed a trial version to implement this idea. The remarkable
feature of this approach is that it can establish the link between the Planck
constant and a macroscopic mass by one single experiment in the most natural
way. Weak dependences on variations of environmental and experimental
conditions, small sizes and other useful features offered by this novel
approach reduce the complexity of the experimental setup. This paper describes
the principles of oscillating magnet Kibble balance and gives details of the
preliminary Planck constant measurements. The value of the Planck constant
determined with our apparatus is h/h_90=1.000004 with a relative standard
uncertainty of 6 ppm.
