Abstract
In an electromagnetically moving device, a magnetic-flux variation measuring unitis placed at a position which is outside a closed magnetic path established when a movable coreand a stationary coreare being attached to each other due to permanent magnets, and at which a leakage magnetic-flux variation due to movement of the movable corecan be measured, so that a behavior of a movable part in a switch, etc. is estimated such that an inflection point time is calculated from the measurement of time-series data of the magnetic-flux variation.
