Abstract

A magnet coil for magnetic Czochralski single crystal growth includes: a first coil, a second coil, and an auxiliary coil arranged between the first coil and the second coil. A distance between the first coil and a first edge of the auxiliary coil close to the first coil is equal to a distance between the second coil and a second edge of the auxiliary coil close to the second coil. The auxiliary coil, the first coil and the second coil have a common central axis. When being energized, a direction of a current in the first coil is opposite to a direction of a current in the second coil, and a magnetic field generated by a current in the auxiliary coil is used for enhancing a cusp magnetic field between the first coil and the second coil.
