Developer’s Description

Detect magnetic field, show its real direction, generate a graph (total magnitude vs. time).

This is an accurate magnetic field detector, featuring a three-dimensional indicator that shows the real direction of the field; it also displays a simple graph of the Magnetic Field (its total magnitude) vs. Time (a 20s interval at 10 samples/second). Our app (portrait orientation, Android 5 or newer) will only work on the tablets and smartphones that have a magnetic sensor. You can use the magnetometer to measure and study the magnetic field produced by different sources (to verify its proportionality with distance, for example), as a detector for magnets and metals and as an indicator for Earth's geomagnetic field.

Features:two units of measurement can be selected (Gauss or Tesla);free app - no ads, no limitations; no special permissions required; this app keeps the phone's screen ON; sound alert when a certain level is reached; the sampling rate can be adjusted (10..50 samples/sec).
