Abstract
A demagnetization method for a multilayer shielding apparatus is provided. In the demagnetization method, the demagnetization is realized on the basis of a demagnetization coil system. The demagnetization coil system includes a plurality of turns of demagnetization coils (), a plurality of connection wires and a power supply module. The multilayer shielding apparatus includes at least two layers of shielding bodies (); all the layers of shielding bodies () are sleeved layer by layer from inside to outside; a plurality of turns of demagnetization coils () are wound on each layer of shielding bodies () at intervals; and one half of each turn of demagnetization coils () is located inside the wound shielding bodies (), and the other half is located outside the wound shielding bodies (). Each demagnetization coil () is connected to the power supply module through the corresponding connection wire.
