Abstract
	In this paper is comparison influence steady magnetic field and alternating magnetic field on value flow stress at compression test. The experiments with the steady magnetic field were make in two parts. The first part was done with magnetic flux, which was opposite direction with direction of motion down tool. The second part was done with magnetic flux, which was identical direction with direction of motion down tool. The experiments show, that the steady magnetic field makes hardening. Whereas alternating magnetic field makes softening. The alternating magnetic field was a similar beginning value of magnetic intensity as alternating magnetic field. In during compress test value of magnetic intensity alternating magnetic field decreasing.
