摘要： A specially shaped coil assembly for accurate adjustment of the magic angle is provided to permit accurate adjustment of an angle made between the direction of a static magnetic field and the axis of sample spinning without impairing the resolution of NMR signals. The sample is placed within the external static magnetic field B 0 . The coil assembly is for use in a solid-state NMR apparatus that performs NMR detection while spinning the sample about an axis tilted at the magic angle relative to the external static magnetic field B 0 . The coil assembly comprises a pair of arcuate conductor lines and a pair of straight conductor lines. Each of the arcuate lines has a diameter of 2 a . Each of the straight lines has a length of 2L. The diameter 2 a and the length 2L are so selected as to satisfy the relationship: 1.91 ‰¤ 2 L / 2 a ‰¤ 2.15
