ABSTRACT:
A circuit arrangement is described for preventing a reaction of a coil on an external high-frequency field of predetermined frequency containing the coil due to a current induced by the field in the coil for a multiple-coil probe of a nuclear magnetic resonance apparatus wherein the coil is coupled via a high-frequency line of predetermined characteristic impedance to a switching element and a circuit unit cooperating with the coil. The electrical length of the high-frequency line between the coil and the switching element is so dimensioned that any undesired reaction of an inactive coil on the other coil(s) is eliminated.
