Distribution of the Magnetic Field in the Gap between Two Permanent Magnets: Calculated and Experimental Data and Their Applications
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 mm 3 near the symmetry axis, a magnetic field with an inhomogeneity of n...
