Magnetscape app analytics for December 19

"Magnetscape" is a new measurement app that observes invisible magnetic fields using the iPhone's built-in magnetic sensor. There are various magnetic fields around us. For example, the magnetic field fluctuates even when a large motor, compressor, or metal is nearby. The earth's magnetic field exists even in places where there is nothing, and we are affected by this magnetic field. "Magnetscape" can monitor the surrounding magnetic field in real time, it can be used for various purposes in real life. For example, it can be used to investigate static magnetic field, search for low electromagnetic field in alternating magnetic field (electromagnetic field), metal detection and more. "Magnetscape" has three kinds of measurement modes for magnetic field observation, please use it according to your purpose. - Scope Perform a graphical display showing the magnitude and direction of the magnetic field. In Scope, the magnetic flux density of the magnetic field is expressed by the size and color of the graphic circle. The display position of the graphic circle will move according to the polarity of the magnetic source, the polarity will be attracted to the N pole if it is the same direction as the geomagnetic field, the polarity will be reversed away if it is the opposite (S pole). If there is no metal or magnetic field nearby, it will be shifted in the direction of the geomagnetism (N pole). - Time Trace the RAW data from the magnetic sensor and its corrected data. It is a time displacement graph of each axis value (Bx / By / Bz) and composite magnetic flux density (Bcomp) in three-dimensional space. You can scroll up to 180 seconds. - FFT Perform frequency analysis on the changing magnetic field. It displays the result of FFT analysis of the composite magnetic flux density. Horizontal axis: Frequency 1 - 16 Hz (0.5 Hz) Vertical axis: dB (ratio to default standard value 45 μT). Reference value can be set in units of 45 ± 15 μT / 1 μT. Features: - Graphical display of magnetic field observation by magnetic sensor (Scope) - Time displacement graph display of magnetic field observation (Time) - FFT analysis (FFT) - Magnetic field observation 　X axis: Intensity (Bx) of the magnetic field of (the right direction toward the screen) 　Y axis: Intensity (By) of the magnetic field of (upward toward the screen) 　Z axis: magnetic field strength (Bz) in the of (vertical upward direction of the screen) 　Composite magnetic flux density: The magnetic field strength (Bcomp) taking into account all three components of the x-axis, y-axis and z-axis. 　Sampling frequency: 32 Hz 　Unit of observation value: uT - Measurement time: 3 minutes - Alert function: A warning message will be displayed if the composite magnetic flux density exceeds 300 μT. - Alert sound function. (Sound Off/On) - Peak hold function on FFT mode. - Angle display function in Scope mode (Angle) - Clock display function in Scope mode. Notes: - The display value of this application is the RAW output data from the magnetic sensor itself. It does not perform any processing such as filter processing within the application. - Since the magnetic sensor is a sensitive device, the internal reference value of the magnetic sensor may be disturbed if exposed to extremely strong magnets and magnetic fields for a long time. - If the reference value of the magnetic sensor becomes incorrect, the magnetic sensor will be automatically readjusted after you stop the application and leave it for a while. If the magnetic sensor is still unstable, please try the electronic compass calibration and reset procedure. Please visit our iOS App Support page for more information on this app.
