## What is Magnetometer / Gaussmeter?

This App turn your device into a Magnetic Strength Meter (DC Gauss Meter).

DC magnetic fields can develop in many steel or iron objects if they have been exposed to magnetic fields, current, or friction. 

This App detects residual magnetism in steel parts quickly and accurately. Simply place the device edge near or against the object being tested, to have a reading representing the magnetism in the object at that site as well as polarity. Will also possible to verify thoroughness of de-magnetizing.
Check out your car, bed frame, desk furniture or any other metal objects you spend time with.
Can also be used to check the strength of magnets.

Features:
- Detect the strength of Magnetic force fields on all three axis’s (x,y,z)
- Switchable units: Tesla, Gauss
- 1 mG (0.1μT) Resolution

Applications:
- Assessment of magnetic materials. 
- Analysis of magnetic circuits and components 
- Measurement of residual magnetis 
- Measure stray and leakage fields 
- Measurement of absolute, and differential fields 
- Testing, sorting, classifying magnets 
- DC and AC motor testing 
- Relay and solenoid test 
- Loudspeaker test

Note: the measure is never 0 because there is the Earth's magnetic field

### 5/5 — Absolutely worth it

*2015-07-27*

I use this App to identify magnetic hotspots in metal. This App does a wonderful job. 
I am also amazed how sensitive the iPhone magnetometer is. For the iPhone 5 the sensor seems to be in the upper right corner of the housing.
I cannot comment on detection of electromagnetic fields, like from high power lines. That is not of interest for me.
I read a lot of negative comments from users of other Apps, so I was unsure to spent money on this App. But for my purpose I am surprised how well this App functions.
