Abstract—Based on our previous and recent magnetic field observations of a chemically peculiar star 53 Cam with the 6-m telescope and literary sources, we can make a conclusion that its magnetic field structure differs from a simple dipole. At the same time the results of measurements from hydrogen lines are described by a simple dipole model. However, data obtained from metallic lines (including magnetic mapping methods) point to a more complex field structure. We performed new observations of the magnetic field in the Balmer series hydrogen lines in the near UV-range. These peculiarities may show that the field strength increases with depth in the atmosphere of 53 Cam.
