The problem addressed by the invention is that of providing a coil having advantageous properties for an oscillating circuit, in particular for a measuring device for electromagnetic signals. This problem is solved in that the coil comprises an electric conductor, the ends of which form the two terminals of the coil. Wound sections of the electric conductor are twisted together, that is to say wound helically around one another. The electric conductor is in principle surrounded by insulation, for example made of plastic or varnish. As a result of the twisting, increases in spacing between adjacent conductor sections within the windings are achieved. This results in an improved quality of the coil.
