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. - 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 testNote: the measure is never 0 because there is the Earths magnetic field
