The results showed that a residual stress during indenting could cause delayed propagation of unloaded indentation crack in humid air. A magnetic field exceeded a threshold field Hth caused instant propagation of indentation crack. A constant magnetic field below Hth could cause delayed change of domain configuration in humid air and delayed propagation of indentation crack in humid air.
