Physics Toolbox Magnetometer
Real-Time Field Strength Meter
Free · In‑App Purchases · Designed for iPad
Real-time magnetometer with live charts, digital display, and 3D arrow view. Record sessions, apply filters, and export data to CSV.
Measure, visualize, and record magnetic fields with precision — right from your iPhone.
Physics Toolbox Magnetometer displays the magnetic field vector in x, y, and z dimensions along with total magnitude in microteslas (µT) or gauss, giving you the data you need for serious lab work or casual exploration.
Three ways to view your data:
- Chart — real-time graph with toggleable axes, adjustable line width, and fullscreen mode
- Digital — large numeric readout for quick at-a-glance measurements
- Compass — live heading with True North and Magnetic North display
Built for the lab and the field:
- Record and export data as CSV for analysis in other software
- Adjustable sample rate from 1 to 100 Hz
- Signal filters to reduce noise
- Detects permanent magnets, electromagnetic fields, and background geomagnetic field
Classroom-ready experiments:
The magnetometer is well-suited for determining the inverse-square law for a point-source magnet, measuring the magnetic field produced by a solenoid, or capturing the periodic field variations of audio speakers and magnetic plate stirrers.
Whether you are a physics student, teacher, engineer, or curious mind, Physics Toolbox Magnetometer turns your device into a capable scientific instrument.
