Apparatus for magnetic flux generation on busbars of a reconfigurable battery

An apparatus for magnetic flux generation on two parallel extending busbars, the apparatus including two clasps that are connected or are to be connected to one another, which are formed from a magnetic material. A respective clasp of the two clasps includes at its two ends a respective connection region for contacting the respective other clasp of the two clasps. When the two clasps are connected to one another, a central region of the respective clasp has a specified spacing from the central region of the respective other clasp. The respective clasp is formed such that, if the respective clasp is inserted perpendicular to and between the parallel extending busbars, a first part of the respective clasp extends below one of the two busbars and a second part of the respective clasp extends above another of the two busbars.
