[iPhone God App] It was found using the Magneto-Vision actually

See magnetic fields on your iPhone/iPad device. Magnetovision generates an image from the x, y, and z components of the magnetometer. Use it to map magnetic fields for conventional or unconventional scientific applications like detecting UFOs and paranormal activity. Draw patterns in the air using a magnet or magnetic object near the device and watch them appear (almost magically) on the screen.

Please note the following:

1) The magnetometer is near the upper right corner of the device.

2) The app is very sensitive. Do not place the device near strong magnetic fields.

3) The location of an object on the screen may be flipped in the horizontal (x) and/or vertical (y) directions depending on whether the magnetic lines of force point towards or away from the device. Use the "Flip X" and "Flip Y" to make the necessary corrections.

4) Tap reset to zero out the earth's magnetic field. Make sure the device is fixed and that there are no other objects near the device when you reset.

5) The false color image auto scales so that the strongest field value detected since the last reset is always red.

6) The slider controls the image smoothing.

N.B. Sometimes the app runs slowly because the magetometer needs to be reset. Simply close and re-open the app. In some cases it may be necessary to power off and restart the device.
