An analytical algorithm for 3D magnetic field mapping of a watt balance magnet
Zhuang Fu, Zhonghua Zhang, Zhengkun Li +4
A yoke-based permanent magnet, which has been employed in many watt balances at national metrology institutes, is supposed to generate strong and uniform magnetic field in an air g…
Coils and the Electromagnet Used in the Joule Balance at the NIM
Zhonghua Zhang, Zhengkun Li, Bing Han +4
In the joule balance developed at National Institute of Metrology (NIM), the dynamic phase of a watt balance is replaced by the mutual inductance measurement in an attempt to provi…
The Improvement of Joule Balance NIM-1 and the Design of New Joule Balance NIM-2
Zhengkun Li, Zhonghua Zhang, Qing He +8
The development of the joule balance method to measure the Planck constant, in support of the redefinition of the kilogram, has been going on at the National Institute of Metrology…
The NIM Inertial Mass Measurement Project
Shisong Li, Zhonghua Zhang, Qing He +4
An inertial mass measurement project, which is expected to precisely measure the Planck constant, , for possible comparisons with known gravitational mass measurement projects,…
