The magnetic domain structures of nanocrystalline magnetic materials were discussed using electron holography. In both soft and hard magnetic materials, the distribution of lines of magnetic flux was found to correspond well to their magnetic properties. An attempt to produce a strong magnetic field using a sharp needle made of a permanent magnet whose movement was controlled by piezo drives was studied. The magnetization process in Fe73.5Cu 1Nb3Si13.5B9 was also elaborated.
