InactiveUS20070046408A1Eliminate wavesMinimize the path and/or shunt membersActive shieldingMagnetsPhysicsMagnet
The present invention relates to a magnet-shunted system for shielding a target from magnetic fields and waves. More particularly, the present invention relates to a magnet system including a path member and a magnet member having a magnet at least partially shielded by a magnetically permeable shunt member. The path member forms a path through which the extrinsic magnetic fields and waves bypass the target, the magnet member serves as a termination point for the magnetic fields or waves, and the shunt member defines another path through which primary magnetic fields generated by the magnet member are confined very close to the shunt and / or magnet members. The present invention relates to various methods of forming the termination point, eliminating the extrinsic magnetic fields or waves by the magnet, and disposing the magnet member into the path member. The present invention also relates to various processes for providing such a magnet-shunted system including the foregoing magnet and path members along with the optional shunt member.
