The temperature dependence of the threshold values of the magnetic fields turned off in WP-mode experiments is investigated. It is shown that the threshold values can be related to the characteristics of the attractor regimes of magnetization relaxation in /sup 3/He-B in a turned-off field. The regime in which the external field is partially turned off and the subsequent relaxation of the magnetization occurs in a residual field of the order of the dipole field is also considered. It is concluded that the fields turned off can have threshold values in this case as well. The existence of the threshold fields is ascribed to the existence of instability and chaotic-state regimes in the spin dynamics of superfluid /sup 3/He-B. The form of the order parameter for the initial phase of the spatially inhomogeneous relaxation in a threshold magnetic field is discussed.
