In order to show magnetic effects clearly, we have designed this tutorial so that it does show magnetic effects clearly; as a result, it doesn't look very familiar. You should see a nearly empty space, containing only a single red particle. A magnetic field runs vertically through this region, as shown by the blue lines. We have drawn two black circles, one directly above the other, to provide points of reference. You can change your view of this region in several ways: clicking on the Top or Side buttons at lower right will shift the viewpoint to the top or side of the black circles; sliding the vertical bar to the right of the region zooms in or out; and clicking the left mouse button and dragging while the cursor is inside the region will shift and rotate the field of view. Try it.
