Abstract
The formation and development of cracks in samples made of ferromagnetic material, cast iron grade SCh 35, which are in a uniformly magnetized state under the influence of an internal magnetic field with a strength of more than 20 kA/m, has been studied. The anisotropic nature of quasi-brittle fracture and the magnitude of mechanical stresses at which fracture occurs are shown. Cracks propagating along magnetic field lines dominate. A possible reason for this is the magnetic interaction between the surfaces of the microcrack.
