On the magnetic field of a finite array of cylindrical ferromagnetic bars--Part I

A new approach is suggested for calculating and measuring the two-dimensional magnetic field of an array of cylindrical ferromagnetic bars in a uniform magnetic field. The field is determined with allowance for mutual magnetization of the bars in a finite array. It is shown that the array can amplify the external uniform field and its gradient to different degrees, thereby increasing the magnetic forces. The method is reasonably accurate and convenient in use; theory and experimental results are in good agreement.
