A method for producing a hybrid circuit having conductor tracks (F1) which are fitted to a substrate (Su), are in each case located between two contact spots (KF1, KF2) and represent fragments of turns of a magnet coil, and having a magnet core which is placed on these fragments (F1) and has an inner hole such that its magnetic lines of force which enclose the inner hole in operation always run largely parallel to the substrate surface. The remainder of the turns is in each case formed by sections (A) of conductor tracks which are placed over the magnet core and are fitted on a carrier (IF) as a metal layer. These sections (A) of the conductor tracks are conductively connected at their one end to a respectively associated first contact spot (KF1) and at their other end to a respectively associated second contact spot (KF2). The production is particularly simplified in that the magnetic core is initially covered with the insulation which adheres to it, at least wherever the sections (A) are located above it and wherever it is intended to be placed on the fragments (F1), firstly both on one side (underneath) and on the opposite side (top), the magnet core, which is now insulated, only subsequently being placed with its insulation on the fragments (F1) or on the segments (A). The magnet core can additionally be wound, for example in the form of a spiral, to form a magnet ring. <IMAGE>
