A resistive magnet, operating at 1.2 T, intended to magnetic resonance spectroscopy in man was set up and evaluated in the hospital of Chamonix. Drusch S.A. in collaboration with Institut d' Electronique fondamentale built the system with the following characteristics: weight: 12 t, pole diameter: 55 cm, distance between coils: 36 cm. Cooling the magnet was provided by water flowing at 50 l/min. The magnetic field homogeneity was 3 X 10(-7) in a 60 mm diameter sphere. Stability was regulated at +/- 1 mGs. Five correcting circuits were used (X, Y, Z, Z2, XY). For experiments in man useful window was 120 X 20 cm and allowed measurements in brain and limbs. With this type of magnet, 1H, 31P and 23Na NMR spectra equalled in quality those obtained with superconducting magnets which work at a very higher cost.
一台工作在1.2特斯拉的电阻磁体在夏蒙尼医院搭建并进行了评估，该磁体用于人体磁共振波谱分析。德鲁施股份公司与基础电子研究所合作制造了该系统，其具有以下特性：重量12吨，磁极直径55厘米，线圈间距36厘米。磁体由流速为50升/分钟的水进行冷却。在直径60毫米的球体中，磁场均匀性为3×10⁻⁷。稳定性调节在±1毫高斯。使用了五个校正电路（X、Y、Z、Z2、XY）。用于人体实验的有效窗口为120×20厘米，可对大脑和四肢进行测量。使用这种类型的磁体，¹H、³¹P和²³Na核磁共振谱的质量与使用成本非常高的超导磁体所获得的谱相当。
