Permanent magnets are integral part of undulator, a device that is used in synchrotrons for production of electromagnetic radiation needed for various kinds of research. To achieve desired properties of radiation it is necessary to have precise magnetic field distribution. Because of this, we need different types of magnetic measurement for production of such devices. One of them is magnetic field homogeneity measurement of permanent magnets. Our goal was to develop measurement device, which enables measurement of magnetic field vertical component above magnet to obtain estimate of magnetic field homogeneity. It would be capable of one dimensional measurement along the magnet and execution of multiple consecutive measurements from different angles for calculation of two-dimensional magnetic field distribution. We made concept of device design, designed the 3D model in Solidworks software and assembled measurement device in simpler configuration (without rotation). We made control program in Python programming language and took one-dimensional test measurement. Measurement repeatability of magnetic field integral value of 6Tmm is approximately 1.6%. With comparison of measurements of multiple magnets that belong to the same undulator we succeeded to detect magnetic field inhomogeneities.
