Abstract: In various engineering and biomedical disciplines often there is a
need to design an electromagnetic arrangement which is able to generate a
magnetic field of demanded distribution. Such a problem also takes place in
magnetic field active shielding designing. In this case solenoids that generate
an opposite magnetic field to the external field in the region of interest are
used. This paper discusses the problem of finding the shape of a solenoid which
produces a given magnetic field magnitude on the axis. Two different methods
are used and compared: iteratively regularized Gauss-Newton method and genetic
algorithm based method with the use of Bezier curves.
Keywords: Active shields, genetic algorithms, iterative methods, magnetic field synthesis, nonlinear inverse problems
