Magnetorheological (MR) dampers are an advanced devices, where the magnetic circuit plays significant role. Manuals for designing of magnetic circuit and its time response does not exist. Not even possible to use analytical equations. There-fore the finite element analysis (FEA) is necessary to use. The FEA cannot be blindly trust. Before we use model based on FEA for final design of the circuit its accuracy has to be determined. The model results are significantly influenced by input parameters – geometry material properties, elements size boundary condi-tions etc. We cannot expect model corresponding to reality without suitable definition of input parameter. This paper aims to compare the results obtained from the FEA, measurement and determine their relative offsets. Experimental device was developed for magnetic induction measurement in the circuit using a magnetometer. The device consists of cooper coil two ferrite cores MR fluid and stand made of polyamide. The device was modelled in ANSYS Maxwell and the transient analysis was performed. The predicted values of magnetic induction correspond with the experiment.
