I would think your problem is that the shutter is really electronic,
and not mechanical to begin with. The click noise you here, is really
an imulation to make it sound and feel like there is a mechanical
shutter.

As for putting a high strength magnetic field near a computer device,
such as your camera, the results would be unpredicatble. If you were to
target a specific point, you will have to have a very well controled
and calibrated magnetic beam of some kind.
