Abstract
Theoretical and experimental studies of the magnetic field distribution in the space between two cylindrical permanent magnets with through holes in the center have been carried out. In the middle of a space measuring 2 × 2 × 2 mm3 near the symmetry axis, a magnetic field with an inhomogeneity of no more than 3% was found and one in the region of 1 × 1 × 1 mm3 with less than 1% was found. Based on the calculated and experimental results, a setup for determining the Verdet constant (V) using neodymium permanent magnets was developed and manufactured. The magneto-optical constants for samples of optical ceramics from Tb2O3 and Tb3Ga5O12 at wavelengths of 0.628 and 1.06 µm are determined.
期刊介绍：
Instruments and Experimental Techniques is an international peer reviewed journal that publishes reviews describing advanced methods for physical measurements and techniques and original articles that present techniques for physical measurements, principles of operation, design, methods of application, and analysis of the operation of physical instruments used in all fields of experimental physics and when conducting measurements using physical methods and instruments in astronomy, natural sciences, chemistry, biology, medicine, and ecology.
