In this work the comparative analysis of the ability to generate a normal force by selected commercially available magnetorheological fluids was shown. For this purpose four types of tests were conducted; a magnetic induction ramp with constant shear rate, a step of magnetic induction without shear and a shear rate ramp with a constant magnetic induction. The aim of the experiments were to examine the influence of the shear on the normal force generated in selected magnetorheological fluids as a result of magnetic field excitation.
