If you need a modern, supported, and more capable tool, consider these open-source and free options: Vizimag 3.19
Vizimag is a specialized software tool designed to provide fast and efficient modeling of two-dimensional magnetic structures, accompanied by intuitive visualization of the resulting magnetic field patterns. It is an ideal educational and research application that allows users to draw magnetic components, define their properties, and instantly simulate the invisible magnetic fields they produce.
The software includes a library of common magnetic materials (like soft iron, NdFeB, and various grades of Alnico). It also allows for the input of custom B-H curves to model non-linear saturation effects. It runs natively on your hardware and provides
Due to the author's passing and the closure of the official vizimag.com domain, the software's licensing status is ambiguous. While the original business model reportedly utilized a followed by a paid registration key, the expiration of the license key servers makes it challenging to legally acquire a permanent license today.
Potential users should note that the original developer has discontinued official support, and the original official website is offline. It is an ideal educational and research application
Vizimag 3.19 is likely a version of software designed for visualizing and possibly editing or manipulating images. The "3.19" suggests it's part of a series, with this being the 19th iteration or version within the third major release of the software.
Despite its incredibly small digital footprint, Vizimag 3.19 packs a robust suite of tools tailored specifically for electromagnetic analysis.
For educators, Vizimag 3.19 is a powerful teaching tool. It transforms abstract concepts like "magnetic flux" into tangible visuals, making it easier for students to grasp how fields interact with different geometries. For professionals, it serves as a "sanity check" tool—a way to quickly validate a design concept before committing to the high computational costs of 3D modeling. Conclusion While newer 3D simulators offer more depth, Vizimag 3.19
