【實用教育app】Magnetic Detector!|最夯免費app-綠色工廠好玩App

With this app you can measure magnetic fields with an accurate precision. You can find magnetic fields in ferromagnetic materials, hight voltage currents or magnets.* Check the real magnetic magnitude.* Three axis values (x, y, z).* Cool graph with the current values (you can check the change between materials).* Alarm (sound and vibration).* You can adjust the tolerance level for the alarm.In other words, this is a MAGNETIC AND METAL DETECTOR.
