0
, but it will not affect the final

so any scale factor cancels out.
For Run #1, Measure the Radius of the Rings for B = 0
Click the Properties icon (shaped like a gear) at the right-hand end of the
movie display toolbar to open the Properties window. In the window, click
“Overlay”. Click the check box to select “Use Magnifier With Tools” from the list
