eTesla

By using data from the phone internal compass,

This app can measure the magnetic field generated from metals

Or high electromagnetic emission from High Voltage line ,Transformer ,

Electric motors,and some home appliance such as microwave oven.

The units of measure is Tesla -T : Nikola Tesla (10-Jul-1856 - 07-Jan-1943)

inventor of the Tesla coil and developer of inductor motor working by alternate current.

The normal earth emissions is around 20-40 T.

High magnetic field can reach 200 T (e.g.
near to speakers).

In very high magnetic field (e.g.
near electric motors ) it can be over 300 T

such high magnetic field ,can easy damage credit ,mechanical watch .

If the phone has been exposed to e high magnetic field , the sensor need to be recalibrate by just shake the phone until the data reader become normal range.

A alarm can be set by the slider, over that value the value become red and the phone will vibrate.

So: stay away from strong magnetic field : find it and avoid it.,
