Description
Measure, record, and analyze magnetic fields in real time using your phone’s built-in magnetometer. Physics Toolbox Magnetometer is a precise EMF and magnetic field meter trusted by students, teachers, engineers, and researchers worldwide.

Four Powerful View Modes
• Chart View
Live graph of magnetic field strength in microtesla (µT) over time across X, Y, Z axes and total magnitude.
• Multi Graph
Compare all axes simultaneously in a multi-panel display.
• Digital Readout
Clean numerical interface for precise real-time measurements.
• 3D Compass
Visualize magnetic field direction in three dimensions.

Advanced Data Tools
• Record and export data as CSV via email, Google Drive, or any sharing app
• Three signal filters: Kalman, Low Pass, and Moving Average
• Adjustable sample rate for slow or fast phenomena
• Switch between elapsed time and clock time on the x-axis
• Fullscreen graph view for detailed inspection
• Customizable plot line thickness

Classroom and Lab Ready

Designed for real scientific investigation. Use it to:
• Verify the inverse square law for a point source magnet
• Measure solenoid field strength as a function of current or coil geometry
• Detect the frequency of magnetically driven objects such as speakers or stirrers
• Map Earth’s background magnetic field
• Locate hidden permanent magnets or ferromagnetic materials
• Demonstrate electromagnetic induction concepts

Comments on Physics Toolbox Magnetometer for Android

★★★★★ Aspen Thornsbury · Nov 6, 2024
This app is amazing for the people who are rating this app 1 star *cough* get a better phone WITH magnetic sensors but this app uses the sensors to see the magnetic field of objects near you but with the people who don't have a more modern phone this app won't work unless you got magnetic sensors there are other apps like this, but they all are tradh and scams there are very few apps thst really use the resources in your phone to make them work this app doesn't crash not laggy and works 100%
★★★★★ Tele Graphe · Jul 16, 2021
Provides nice graph and numeric display of magnetometer sensor
★★★★★ Stephan Tolstoï · Jun 19, 2025
Works fine. It confirmed my watch got magnetized.
★★★★☆ Avi Jain · Apr 23, 2026
It's a good app but technical issues. Max sampling rate of 100Hz defeats the purpose. Most appliances in North America are at 60 Hz. sampling rate below 120 Hz won't work. Also it packs accuracy. Measured sampling rate is 65 Hz while by default it claims as 100 Hz.
★☆☆☆☆ Charles Keating · Aug 5, 2019
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.
★☆☆☆☆ Aaron H · Jan 20, 2017
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.
