Summary:

- Researchers from China have developed an electromagnetic vortex cannon, a device that can generate and project powerful electromagnetic vortices.
- The vortex cannon uses a coil-based electromagnetic launcher to create a toroidal vortex of electromagnetic energy that can be directed and projected over long distances.
- The device has potential applications in areas such as wireless power transmission, electromagnetic shielding, and non-lethal weapons, though further research is needed to fully explore its capabilities.
