Results on the large gyromagnetic effect observed in FeSiB amorphous wires are reported. This effect consists in the appearance of a sample rotation around its axis. with frequencies from 1 to 60 Hz, when the sample is subjected to an axial alternating field of ∼102 A·m-1 with a frequency of ∼104 Hz. The observed experimental characteristics of the effect indicate that its appearance is closely related to the formation of a magnetic standing wave associated to the 180° domain wall movement from the axially magnetized inner core of such wires. The magnitude of the wire's magnetostriction constant plays an essential role as concerns the macroscopic rotation of the wire.
