Claim 19:
20. A local coil comprising:
at least one coil element in the form of a loop, the at least one coil element comprising:
a first conductor;
a second conductor;
a third conductor;
a first dielectric; and
a second dielectric, wherein the first dielectric is arranged between the first conductor and the second conductor, and wherein the second dielectric is arranged between the second conductor and the third conductor;
a receive unit that comprises the first conductor and the second conductor;
a detuning unit that comprises the third conductor,

wherein in a first operating state of the at least one coil element, the receive unit has a first resonant frequency as a resonant frequency,
wherein in a second operating state of the at least one coil element, the detuning unit is configured to detune the resonant frequency of the receive unit so that the receive unit has a second resonant frequency as the resonant frequency, the second resonant frequency being different than the first resonant frequency,
wherein the detuning unit further comprises a switch element that is configured to:
electrically interrupt the third conductor in the first operating state; and
electrically short-circuit the third conductor in the second operating state.
