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 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!

I Need This!

Just when I thought I had everything. Definitely a cool app with a multitude of uses. Nice Interface good online manual and works exactly as advertised.

Vice nice

This is an excellent app, doing everything that is advertised. The arrows give a clear view of the direction of the magnetic field and the acceleration. They are a lot easier to visualize with this than by looking at the raw sensor numbers. I especially like the magnetic declination view. This is useful for learning about magnetism as well as seeing what kinds of fields are emitted by various devices around the house.

Responsive and precise

If you wanted a tricorder, get this app. The arrow reflects magnetic flux very quickly and shows the field strength in real time. It's 99 cents and does a fantastic job of representing 3d magnetic fields. The new version has the compass overlay working correctly. I've bought only a handful of apps and this is one. It's a very impressive app to anyone who is science minded.
