Physics Toolbox Magnetometer
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 classroom, 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 stirrers.

No-nonsense, clean, snappy - instantly useful to me! Would love to also be able to stream readings over network.
Nice! Graph is well done. Also the absence of ads is so rare these days. Thank you!
Excellent app I've tried quit a few app but this one by far the best. No issues at all works perfectly. thanks for an awesome app..
Very useful tool for measuring ambient magnetic field in all three directions.
Amazing, unbelievable it's available for free, big thanks for devs!
Love this app simple to use and it seems to pick up everything I was trying to measure around my phone (magnetic field)
Three axis magnetometer is very sensitive and works well on the S8.
is it possible to use this magnetometer to measure earth's magnetic field if left static in one place?
The graphs are clear and animate smoothly!
This one is the best! I can see the north or south pole of magnets....
Provides nice graph and numeric display of magnetometer sensor
Very interesting application! Working on ways to make use of this app...
Simple to use. Serve the purpose.
It is great it does everything i wanted.
if you value your privacy, you will steer clear of this app! This app records your ENTIRE file cabinet and you are UNABLE to delete it.
Good app , great to have it
LOOK, EVEN I CAN USE IT.
moment of clarity
Great app. Obviously not as accurate as actual equipment but there you go. To the moron who reviewed "Tilt phone left, total magnetic field strength 10. Tilt right, total magnetic field strength 70. I doubt it. Really heavy focus on displaying which way the phone is aiming." MAGNETIC FIELD STRENGTH IS A VECTOR FIELD. HALL PROBES ARE DIRECTIONALLY SENSITIVE. For christ's sake do some research before spewing s**t onto the internet
Great for learning and thinking about how the sensors can be used in new ways! Thank you for your work. Functions well on LG Stylo 3+.
Raw data, csv file, have fun, a portable magnetometer that can be fired at will to discover things around you you didn't know where there!!
Too many apps do'nt include include such a convenient data log. Operation is intuitive and reliable. Thanks!
Needs alerts. Other than that - cool app, and great and quick response from the Developer !
HTC One A9 - Great App..One thing to keep in mind,,if a strong magnet comes near,you'll magnetized your internal compass,which could then throw off gps,& this app..
Very useful tool
Works great and is ad free!!!!! This is such an easy to use app. Its intuitive interface and multiple options for how to display the data make this a winner.
