**NEEDS TO RUN IN TURBO MODE** -Multiple charge interactions Use mouse to click charges into existence, move them around, change their charge, or delete them. -Equipotential force lines (color background) Turned on and off by holding the space key down. -Field Vector force grid (arrows) Turned on and off by double tapping the space key. -Test Probe (gives field strength and direction) Turned on and off by using "P" key to toggle. -Field lines (iron filings) placed with the "F" key. Removed with the "R" refresh key.
Original idea from project by dapontes. https://scratch.mit.edu/projects/10032652/ Forces calculated by summing q/d^2 (charge) Like charges repeal, opposite attract. Can be used to help visualize electric, magnetic, or gravitational (make all charges negative) fields.
