Quote - Q: I can't get the hang of using Poser magnets. How do they work?

A: PhilC has an excellent "Magnets Video"  tutorial (there is also a text version). I highly recommend that you take a look.

 

Watched it. He never says how to resize the circle that determines the area affected by the magnet.  A newbie (such as myself) might assume that you resize it by clicking on it and dragging, but that doesn't do anything. I figured out that you move the circle by clicking outside of the circle and dragging, but nothing I have done so far has resulted in any change in the size of the circle.  These are the kind of things we need explained.
