WebIn December of 1945, Bloch and Purcell met at the annual meeting of the American Physical Society and realised that they were working on similar problems. They decided … WebBloch was married and had four children. Work Protons and neutrons in nuclei act like small, rotating magnets. Atoms and molecules therefore align in a magnetic field. Radio waves can disturb their direction of rotation, but only in certain stages, in accordance with quantum mechanics.
