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!

Bof

Ces pas fiable

Bonne application, pour technicien...

JeuLeuVeu · 16 years ago

Application interressante, surtout si on fait de la conception de systèmes électroniques (ce qui est mon cas) et quon utilise des accéléromètres et des capteurs magnétiques. Je regrette quil ny ait pas les indications directes des valeurs sur les axes X, Y, Z, et le calcul des angles pitch et roll. Lessentiel de lapplication est réalisé, il suffirait dajouter quelques affichages pour quelle soit vraiment interressante. Il pourrait aussi être interressant davoir un log des valeurs magnétiques et daccélération, avec des intervalles de temps programmables...

a priori ça fonctionne

Scalaire · 15 years ago

a priori ça fonctionne, je nai pas toucher au reglages, mais ça marche jai promener comme dans la video un aimant autour et ça le suis bien regalge a affiner car je ne comprends pas chez moi pourquoi il indique toujours le sol dun peice a un endroit precis ou peu etre quil y a quelquechose la ??? ok qur iphone 4 apli tres bells visuellement

Plutôt bien pour une appli gratuite..

olerca · 15 years ago

Visuellement bien réalisé, peu faire de la mesure empirique de champ magnétique et remplacera un gaussmetre de base....jai bien dit EMPIRIQUE..

Instructif

Je ne sais pas si la modeste utilité de cette application mérite quelle soit payante (certes bon marché), mais si vous tombez sur lun des jours où elle est offerte, nhésitez 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.
