초록
Thomson's jumping ring was first exhibited by Elihu Thomson in 1887 and modified to include the floating variation by John A. Fleming in 1890. This vivid demonstration of electromagnetic induction is still used in physics classrooms to illustrate Faraday's and Lenz's laws and is the basis for linear actuators for sorvo-mechanical purpose as well as induction heating and rail guns. The jumping ring apparatus of the type described in this study is used to demonstrate and educate the effects of electromagnetic induction. To verify control algorithm, a sensor system and a data control/measurement system is required. The sensor system consist of photo-interrupted and encode circuit which is designed to take voltage according to the position of ring.
