Abstract

A method is proposed to achieve uniform magnetization in ferromagnetic samples based on the bionic parametric optimal synthesis of the magnetization source that provides the necessary magnetization distribution. Simulation results are reported that illustrate the efficiency of the method. Numerical examples show that the proposed method allows the achievement of more uniform magnetization in short samples by using a magnetization system with ferromagnetic elements.
