PURPOSE:To better cooling effect and suppress electromagnetic force reacting radially along a super-conductive coil, by bonding an inner winding of a super- conductive coil with a bonding belt composed of a nonmagnetic material almost in the middle of a super-conductive coil. CONSTITUTION:An inner winding 1A is bonded with a bonding belt 9 made of nonmagnetic material via a belt 7 made of insulating material in the middle of a super-conductive coil 1. The inner winding 1A of the super-conductive coil 1 produces higher electromagnetic force than an outer winding 1B. Only bonding force of the super-conductive wire itself does not endure this higher electromagnetic force. The outer winding 1B produces lower electromagnetic force and bonding force of the super-conductive wire itself can endure it. Therefore, the super-conductive coil 1 is bonded in the middle by winding nonmagnetic material. The electromagnetic force reacting radially against the inner winding 1A is suppressed, and a supporting device can be voided. |
