Abstract
The disclosed coil is for a strong AC magnetic field generator with coaxially laminated eddy-current carrying conductor disks each of which disks have a central hole and a radial slit. Each turn of the coil consists of an annular conductor plate disposed between adjacent disks and each turn is insulated from the adjacent conductor disks by insulation rings inserted between the annular conductor plate and the adjacent conductor disks. The annular conductor plate and the insulating rings in each turn of the coil have radial slits. The slits in one coil turn are aligned in a radial direction, but the slits of adjacent coil turns are angularly displaced with respect to the central hole of the conductor disk. A slitted end of the annular conductor plate of each coil turn is connected to that of the immediately neighboring coil turn through the radial slits of the conductor disk and the insulation ring.
