A precision electromagnet generating a magnetic field with an induction ranging from 0.05 to 0.50 T is designed, manufactured, and studied. It is intended for a magnetic resonance mass spectrometer with a rated resolution of about 10(6). The magnetic field inhomogeneity on a circular orbit with a diameter of 400 mm along which the ion beam moves is no more than +/- 1 x 10(-5) of induction B-0 at the center of the magnetic gap. At any point of the orbit, the magnetic field is kept constant with an accuracy of higher than 10(-6) for several minutes, which is sufficient to record mass spectra.
