Yp Electric Field

YP Electric Field simulates up to 26 electric charges (located in the same plane) and draws the lines of force, the equipotential lines and the electric field vectors in the area surrounding the point charges. The user can move the charges and change their numerical value. A probe measures the electric potential and the magnitude and direction of the magnetic field at any position. System Requirements: YP Electric Field runs on any Macintosh computer with MAC OS 7.0 or later. It needs about 250 Kb on your hard disk and 1 Mb of RAM. The software runs on older models with 68000 processors (Mac Plus, Mac Classic), but simulations are slower.
