Magnetometer 3D

Microsys Com Ltd.

About this app

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)

Ratings and reviews

(update) I changed the settings to higher field levels and then started working correctly. Now 4 stars. (initial review) The 3D arrow is using data from the accelerometer, not the magnetometer. So just pointing to the center of the earth. It could have 5 stars if fixed.

Awesome app. The arrow points in the direction of magnetic north. Perfect for identifying a magnet's polarity.

totally random & inaccurate.
