Device for protecting a space adjacent to a magnetic source, and method for manufacturing such a device

#The invention relates to a device which allows a space adjacent to a magnetic source to be protected.

#The magnetic energy radiated into a space adjacent to a magnetic source can disrupt the operation of electronic devices (electromagnetic compatibility) and/or present a danger for a human being who occupies this space when this energy results from a high power even over a short duration or from a weaker power to which the human being is, however, exposed over a longer period of time.

#Generally, such a device comprises a multilayer shield or screen, such as, for example, that described in document EP1399929. The shield disclosed by this document is wound around an electric cable. It comprises at least two layers of ferromagnetic material.

#The invention will be better understood using embodiments of a device in accordance with the invention with reference to the appended drawings, wherein:

#FIG. 1 is a schematic view of a device in accordance with the invention;

#FIG. 2 is a schematic view of another device in accordance with the invention;

#FIG. 1 shows a device 1 for protecting a space 2 adjacent to a magnetic source 3 against magnetic energy radiated by the source 3.

#Such a device is necessary in many fields in order to protect a human being against the magnetic energy radiated by apparatuses which are, moreover, useful therefor.

#In particular, the vehicle 22 shown in FIG. 4 comprises wheels 24, 25 and a machine 23 for driving all or some of these wheels. The machine 23 is controlled by an electric power supply 13.
