Abstract: A laboratory magnetic resonance imager for small objects that operates in a field of 7 mT is described. The hardware of the tomograph makes it possible to perform experiments on different nuclei and to use double irradiation methods. The high degree of absolute uniformity of the constant magnetic field allows the use of relatively weak gradients to obtain images. The tomograph can be used to develop new methods of magnetic resonance imaging for the purpose of training physicists and engineers in the methods of obtaining magnetic resonance images and for the study of small objects.
