I wasn't talking about the magnet and base, I was talking about the base and zone, as you mentioned. The screenshot was just a point in time, I had moved the magnet, independent of the base, all over the place, the screenshot just showed where it happened to be. Bur even that small movement, once all ws said and done, did show a marked effect. The relation of the magnet and base to the zone are irrelevant, it's the relation of the magnet to the base that produces the effect.
