Abstract
The invention relates to a method for analysis of magnetic fields or signals used for the determination of the position of an object, wherein two temporally to each other shifted magnetic signals or fields are generated by two conductors arranged at least in part or completely separated from each other. The magnetic fields generated by the conductors are consecutively being captured by at least one and preferably three sensors arranged orthogonally to each other and determining from the captured signals information for determining the position of the object carrying the sensors relative to the conductors.
