ELECTRON-optics methods have by now found wide application in the investigation of various magnetic structures. Contributing to this were the sufficiently high resolution, good contrast, high sensitivity to the deflecting action of magnetic fields, and the practical absence of electron inertia, making it possible to observe the dynamics of fast processes. The present article is a review of electron-optical methods of observation, and of qualitative and quantitative estimates of magnetic structures on the surface of bulky objects. The results obtained with the aid of other methods can be found in [1-4].
