Abstract
A distributed demagnetizing coil system, a shielding device, and a demagnetizing method. The system includes turns of demagnetizing coils evenly wound on each shielding surface of a shielding body in the shielding device at intervals and connecting wires provided on outer side of the shielding surface in an inflection manner. One half of each turn is located on inner side of the wound shielding body and the other half of each turn s located on outer side of the wound shielding body for providing corresponding demagnetizing magnetic fields to form a closed magnetic flux loop. One half of each connecting wire is connected to the corresponding demagnetizing coil, the other half of each connecting wire is reversely inflected along an original path and is connected to a power supply module, so that corresponding demagnetizing current is introduced into each demagnetizing coil connected to the connecting wire.
