ViziMag - Version 2.0 A program to allow the very fast modelling of 2D magnetic structures, and the visualization of the magnetic field patterns. Both magnetic field lines and magnetic flux density can be viewed and measured. Several common magnetic structures have built in models, and many editing tools are provided. A database of preworked examples is supplied, and these can be run and modified. A website gives a forum to exchange views, and also has a gallery of examples. Tutorials in several languages are available on the website.
