Description
The first and only Vector Magnetometer on the iPhone - Visualize the hidden world of magnetism around you in 3 dimensions (3GS or later!)! It can be perfectly used to explore and measure the direction and strength of the magnetic field of random objects around you (which can be quite fascinating!). With limitations (see docs) it can be used as a metal detector to find electric lines or pipes in walls (always good to check a wall before drilling in, at least better with this than not to check at all). Another application is to use this tool as a rough estimate of your north-south position on earth without using the GPS(!) - just by measuring the local earth magnetic declination (it works fine even while flying in a plane to check how the declination changes). Or simply explore your next Christmas present before opening it! Send us your results!
The application has four different displays modes to visualize the magnetic field:
- Absolute Mode: Displays the absolute magnetic field in microtesla (μT) measured by the magnetometer.
- North Mode: A compass head-up displays the geographic north along with the pointer that directs to the magnetic north (thus display difference magnetic to geographic north).
- Declination Mode: Two arrows will be displayed to indicate the declination of the earth magnetic field (0° just on equator, increasing to north with blue pointer direction up or south with blue pointer direction down).
- Relative Mode: This mode shows the relative strength (absolute minus compensation vector) of the magnetic field in μT.
… and five different display modes for acceleration visualization:
- Absolute Mode: Displays the reverse acceleration of the iPhone (1g up when hold steady).
- X-Rotation - Y-Rotation - Z-Rotation: The arrow will display the rotation around the X-, Y- and Z-Axis of the iPhone. The digital indicator shows the angle numerically (-180° - +180°). A way to calibrate will be added with one of the next updates, so you could use this as a level.
- Relative Mode: This mode shows the relative strength (absolute minus compensation vector) of the acceleration.
For a detailed documentation, please visit our product homepage.
For recreational use only. However it CAN (!) be very accurate. The measurement is performed as good as possible (we try our best) by using the inbuilt accelerometer and magnetometer to their limits. The range of the accelerometer typically has a max of ±3g (~4.2g displayed here if combined) and each magnetometer usually recalibrates internally when over ±120μT in one axis. However, tell us your experience!

Ratings and Reviews
Bonne application, pour technicien...
Application interressante, surtout si on fait de la conception de systèmes électroniques (ce qui est mon cas) et qu'on utilise des accéléromètres et des capteurs magnétiques.
Je regrette qu'il n'y ait pas les indications directes des valeurs sur les axes X, Y, Z, et le calcul des angles pitch et roll. L'essentiel de l'application est réalisé, il suffirait d'ajouter quelques affichages pour qu'elle soit vraiment interressante.
Il pourrait aussi être interressant d'avoir un log des valeurs magnétiques et d'accélération, avec des intervalles de temps programmables...
Instructif effectivement
A mon tour de poster un avis, le précédent datant d’il y a 10 ans… En plus de montrer la direction du champ magnétique en 3D, je vous invite à le passer au-dessus d’un matelas à ressorts, vous serez sans doute surpris.
Instructif
Je ne sais pas si la modeste utilité de cette application mérite qu'elle soit payante (certes bon marché), mais si vous tombez sur l'un des jours où elle est offerte, n'hésitez pas. Elle permet en effet de montrer à vos enfants/amis (ou à vous-mêmes) la réelle direction du champ magnétique terrestre, dont la composante horizontale sentie par les boussoles est en fait assez petite comparée au vecteur total.
