磁力支持天秤による回転球に働く空気力の測定

抄録

We used a Magnetic Suspension and Balance System (MSBS) in order to make accurate measurements of the Magnus force acting on a rotating sphere. The MSBS levitates the model by controlling the magnetic forces using electromagnets. Since the model is levitated by the MSBS, there is no support interference. We succeeded in measuring the Magnus force on the rotating sphere without the use of a physical support. It was measured that the Magnus force coefficient increases with increasing the spin parameter.
