【 摘 要 】

The measurement of Newton's constant G has a relatively long history. However, G is the fundamental physical constant with the largest uncertainty of any fundamental physical constant up to now. To resolve the discrepancies in the value of G, a measuring system based on a new principle is needed. In this paper, we describe the development of a new machine for generating nano-torque by electromagnetic force based on the principle of the Kibble balance method, and a new method for measuring G using this machine.
