Abstract: The magnetic field of a linear current and a big ferromagnetics plate with a semi elliptic cylindrical raised is studied by using conformal mapping and magnetic images method. Its magnetic vector distribution and magnetic induction line equation are obtained. The magnetic induction line maps are plotted by using the software MATLAB.

Key words: linear current, a big ferromagnetics plate with a semi elliptic cylindrical raised, conformal mapping, magnetic image method, magnetic vector, magnetic induction lines, numerical simulation
