Abstract
We propose a novel magnet structure for magnetic resonance imaging. The design made use of the CALMAG3D code which features high precision and high speed calculation and requires relatively small computer memory. The magnetic field at any point in space can be calculated without using the classical methods of finite elements, conformal transform, boundary limit conditions, and matrix inversion
