A magnetic parking sensor including a detection device for detecting geomagnetic measured values in the region of a parking space in three coordinates; a first-in, first-out memory device into which the geomagnetic measured values are loadable; and an ascertainment device. The ascertainment device is configured to map the x and y components of the geomagnetic measured values into complex numbers, the complex numbers being ascertainable depending on the variability of the defined number of the geomagnetic measured values; to define a number system having a defined number of elements in accordance with the variability of the geomagnetic measured value and of the complex numbers; and to ascertain an availability state of the parking space by ascertaining a root λn of the polynomial λ3−(2n−1)λ2−(n−1)2λ−(n2+1), where n=variability of the geomagnetic measured values, λ=auxiliary variable of the number theory.
