Abstract (en)
[origin: EP2511918A1] The method involves allowing current to flow through a magnetic coil (2), where the current creates a magnetic field in the magnetic coil. A controllable switching element (S-1) is arranged in a discharge line (4) of the magnetic coil. The switching element allows separation of the magnetic coil by a supply voltage during a time period. A voltage pulse (U-I) is generated in the magnetic coil, and time course of the pulse corresponds to a location of an object. The voltage pulse is transmitted to an evaluation unit (5) for determination of position of the object. Independent claims are also included for the following: (1) a device for determining position of an object with respect to a magnetic coil of an electromagnet (2) an electromagnet.
