Since the end of the 1970s Christina Kubisch works with the system of electromagnetic induction, which she developed from the basic technique to an individual artistic tool. In 2003 she started her research on a new series of works in public space, which trace the electro-magnetic fields of urban environments in the form of city walks. The first Electrical Walk took place in Cologne in 2004.
