A electric, magnetic, and gravity field physics presentation program
BeamFlow is a scientific presentation and demonstration program for typical introductory physics problems involving electric, magnetic, and gravity fields in three dimensions. Real-time demonstration of the magnetic field around a wire, the gravity fields around rotating binary stars, and the electric field from multiple point charges are just some of the potential applications.
