CrowdMag App DESCRIPTION

CrowdMag is a tool that measures the local magnetic field using your smartphone! The app displays the data as a graph or a map in units of nanotesla (nT; one nanotesla equals 10^−9 Tesla). The local magnetic field components measured by CrowdMag are the Z (downward component), H (horizontal intensity), and F (total intensity). Use CrowdMag for measuring magnetic data during your outdoor adventures or to conduct your own homegrown science! To perform your own experiments or analyze your observations, export your data as a CSV file. Optionally, your magnetic data may be shared with NOAA to help scientists understand more about Earth’s magnetic field!

What is new!

CrowdMag is going active! When you go out for a walk, run, or other outdoor activities, use CrowdMag to measure the magnetic data along your path and save the data as a “magtivity”. Save, list, export or delete magtivities to create a complete magnetic field map of your area. We particularly encourage you to share your magtivities with our research group at NOAA and to have multiple magtivities along the same path so that we can stack the data to reduce the noise.

Getting a new phone? Don’t worry! You can now export a backup of your CrowdMag and save it on your computer. If you have to reset your phone, or switch to a new phone, you can now import your backup and continue using CrowdMag without losing your status for data contributed, areas covered, or magtivities completed.

CrowdMag’s magnetic calculator provides magnetic variation (declination), the magnetic field’s dip angle, total magnetic field and other magnetic field components (as well as their associated uncertainties) based on the latest World Magnetic Model (WMM2020).

CrowdMag Features:

– Create your own magnetic activity (magtivity)
– Customize recording frequency and location accuracy
– Interactive Google Map provides a map of your magnetic data
– Graph your data as a time series line chart
– Check the quality of the data by comparing it with the WMM
– Export your data as a CSV file
– Clear stored data on your phone
– Optionally share your data with NOAA
– See generalized crowdsourced magnetic data from other users
– Live magnetic compass
– Current solar magnetic disturbance
– Expected magnetic field calculator
– Uses the most recent magnetic field model (WMM2020)
– Export data via email, Google Drive and other options
– Export CrowdMag backup to save your contributions’ status and data
– Import CrowdMag backup (works across different phone platforms)

Displays a graph of Magnetic Field vs.Time graph in x, y, z. Export as a .csv
This magnetic field sensor app measures and displays a graph of Magnetic Field (µT) vs. Time (s) that in x, y, and/or z dimensions, as well as total magnitude. By accessing settings, data can also be displayed with a digital read-out.Total magnitude magnetic field strength can be recorded and exported in an e-mail or through Google Drive as a .csv attachment using a comma or a semicolon as a delimiter. Click on settings to plot data against elapsed time or clock time, to change the plot line thickness, or to change data collection rate. A brief tutorial upon start-up gives an overview of how to use the app.The magnetic field sensor can measure the background magnetic field of the earth and be used to check for the presence of permanent magnets or electromagnetic fields. Within the claoom, the magnetometer can be used to determine the inverse-square law for a "point source" magnet, to determine the strength of a field produced by a solenoid, or to measure the frequency of objects with magnetic variations, such as audio speakers or magnetic plate..

Computation of solar time and simple solar ephemeris for gnomonist
The main function of TpSol is to give the solar time according to the legal time and the GPS location, but TpSol makes much more:It supplies the equation of time and the solar declinationIt indicates the azimuth and the altitude of the SunIt draws the shadow of the Sun on a sundialThe sundial can be drawn according to the orientation of the smartphone or the tablet. In this case, TpSol uses a magnetic sensor that it is necessary to calibrate in this way:Be sure that no metallic object or magnet is in the surrounding of the device (think to the magnetic lock of the smartphone protection)Activate the dynamic drawing of the sundial (button 'Auto' of the group 'Towards')Turn slowly the smartphone or the tablet on the three axes: 2 to 3 revolutions during about 10 seconds per axis.The calibration is finish. The parameters of the sundial orientation (inclination and declination), which are computed and supplied by TpSol from the magnetic sensor, are then less erratic and more accurate. However, the accuracy is not better than some degrees.

App REVIEWS

Rand

I use the app to determine magnetic declination at my location. It works well, but I have a suggestion as to the readout of the declination. BY CONVENTION, positive declination is east and negative declination is West. As I sit here, that is easy to remember. In the field, it may not be. To reduce confusion when setting the declination on a compass, which marked East and West, but NOT +/-, how about reporting the declination like this: 10.43 (E), or -10.43 (W) Adding this would be a big help.

sayed

Very useful for geophysist

Andr

Awesome app. It helps when setting up my telescope outdoors.

Guest

Love it. Have been using for about a year. Excellent app. Quick response on questions, too.

Marijan

Error writing .csv data file when trying to export measurements. Please, help!

Amanda

We love the app! I fell sensitive about the electromagnetic waves and radiation and we are specially today experiencing a high level variation from our pattern. We live in the middle of south America and we saw an incredible increase of our numbers. From 23.000nt to 149.000 and it's not going back normal! From 02 Jan 2021. Even our phones started to break with no apparent Reason....

Vox

Look no further. CrowdMag is by far the best compass/declination app in PlayStore. Free, fast, feature-rich, and no ads.

Ericka

Fun app!

Vlad

Good good good

Tina

Fun app. It needs to have a function to overlay readings from different dates for the same location. Also more choices of maps would be so cool! My choice would be a LiDar map and Arial would be my second choice.

Glyn

Great until it got censored

Andromed..

Easy to use and always on point.

John

Ok on HTC...does not work on my new phone

Stanley

It would be cool if CrowdMag linked with MyShake extra points if it used a geo coin too

mydevice..

Is permanent recording good idea for battery? I think, previous "taking of samples" was better...

joe

So far it seems to be accurate, also very useful, also thank you for being

Guest

Good Crowdsouring application on earth magnetic deviation and its impact.

Steve

Very interesting... best of its kind!

Mindy

i just downloaded this and was interested to know if you can record data on the poles shifting? like does it show you data on true north vrs a year from now how much it's moved? thanks !

David

My last review was wrong. I needed to calibrate for the compass to work properly
