App Description
An accurate magnetic field detector that features a 3D indicator of the field.
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 per second). Our app (portrait orientation, Android 6 or newer) will only work on 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 are 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 per second)
