Abstract
A method for detecting magnetic fields, particularly for detecting the position of objects with a preferably oblong, soft-magnetic element, which is connected to electronics, with via the electronics the impedance of the soft-magnetic material is measured, characterized in that a magnetic field is used in which by the position of an object which is located in an arrangement with the soft-magnetic material the magnetic field develops at the location of the soft-magnetic material, with the magnetic permeability μ of the soft-magnetic material adjusting, depending on the magnetic field and thus the position of the object. A respective device serves for applying the method according to the invention.
