The accurate description of magnetization is crucial for designing devices with soft magnetic cores. MagAnalyst is an easy-to-use MATLAB toolbox that models the magnetization of soft magnetic materials. It implements a physically based approach, proposed by Silveyra and Conde Garrido, to describe the ideal anhysteretic curve. The equation of state is simple yet accurate for various material scenarios. The toolbox first plots a set of curves to help the user determine the number of component magnetizations to model and the seeds for the fitting process. It then retrieves the model parameters without the need for programming or optimization skills. As a result, even noisy data from challenging scenarios can be accurately described by a single analytic function, with continuous and differentiable magnetization and susceptibility. We believe that MagAnalyst will be a valuable resource for the magnetic materials community.
You need to create a copy on a local directory on your machine to use MagAnalyst. Obtain a copy by downloading and unzipping the latest release or clone MagAanalyst instead e.g. using: git clone https://github.com/matias-gonz/mag-analyst. You can place the MagAnalyst folder anywhere on your machine.
We recommend using GitHub Desktop, which allows users to easily synchronize with the latest version of MagAnalyst.
After downloading the main folder and placing it in a suitable location, MagAnalyst is ready to use.
We recommend using the C:\ drive for the proper functioning of the project samples here provided. Otherwise, after opening a sample project you will need to import the curve sample file again.
To start using the application with the graphical user interface, simply run the app.mlapp
file.
If you prefer to run MagAnalyst using command lines, you can follow the instructions in the mag-analyst\src\demo.m
and mag-analyst\src\demo_2_components.m
files.
MagAnalyst was implemented and tested with the Matlab 2022b version on Windows 10. Authors cannot guarantee that the code can run on previous versions.
