Abstract
A device for heating of railway tracks is provided. The device comprises a magnetic field generator fed with a low-frequency current. The magnetic field generator is formed by a device without a circuit returning a magnetic flux generated by the magnetic field generator. Hereby the magnetic flux can be returned via a heater. The heater is a material generating heat when placed in the magnetic field. The heater can be the railway tracks or a plate provided in conjunction with the railway tracks.
