Abstract:
A magnet for use in magnetic resonance spectroscopy, comprising a magnet extending along a z axis and a y axis, the magnet having a primary section with only one first coil forming an inner part of the primary section of the magnet and at least one group of second coils having a larger radius than the first coil, the second coils are located on and extending along a first line parallel to the z axis for a first predetermined distance and are spaced from one another along that line, the coils being wound so that the first coil has a current density opposite that of the said group of second coils which has a larger number of ampere turns than the ampere turns of the first coil and the first coil extending along a second line parallel to the z axis for a distance greater than 50% of the first predetermined distance.
