In this simulation, you can play with the direction of the magnetic field and the magnitude and sign of the charge to draw patterns on the screen. Explore the different patterns you can make. See how long you can run the simulation without the trail crossing and without the charge going outside the grid. Note that the field is either into the screen (marked with x's) or out of the screen (o's).
