摘要
A magnet for NMR well logging comprises two opposed sets 10,11 of elongate, parallel and abutting HTSC coils. The magnet produces a uniform field in an external working region 6. The position of the working region may be altered, for example by displacement to one side of the magnet (figure 2), by adjustment of the gaps between opposed coil pairs and adjustment of coil lengths. The magnet may also be applied to medical imaging and to spectroscopy. The fields of the two sets may be opposed or aligned.
