| Outline of Final Research Achievements |
In order to establish a micro torque measurement technique, I designed and developed a new torque generation machine based on the watt balance method. I carried out two different experiments by using this machine. First, I evaluated the magnetic passing through the rectangular coil by measuring the angular velocity and induced electromotive force when the rectangular coil installed in a homogeneous magnetic field was rotated by a motor. Second, I measured micro torque generated when the electric current flows through the rectangular coil by using the same machine. The uncertainty of torque realized by this machine was estimated as a trial calculation. As a result, SI-traceable micro torque was successfully realized for the first time using a method which does not rely on the gravitational force.
