Metal Detector

Normally range of magnetic field is measured at approximately49μT(490,G, 1μT=10)

This app uses magnetic field sensor on your phone to detect and measure electromagnetic waves.

Normally range of magnetic field is measured at approximately 49μT(490,G, 1μT=10mG), but it increases when metal or magnet is nearby.

Use of this app is rather simple.

Open this app from your smartphone and attach or tap it nearby.

Note: this is not a professional device. There's a possibility of an error as a each smartphone has different sensor.

Magnetic wave is rated at 30μT on the earth but it could measure slightly higher on this metal detector. Margin of error increases near the north pole.
