The magnetometer sensor of the iPhone is switched on and<br \/>\nthen the car starts moving. The iPhone\u2019s magnetometer is stimulated throughout its movement along a<br \/>\nstraight line. A \u2018sensor Kinetics\u2019 application on the iPhone saves the magnetic stimulations and<br \/>\nproduces a graph of the changing magnetic field near the iPhone. At the end of motion, data from the<br \/>\nmagnetometer is interpreted and peaks on the graph are detected. Thus, position-time changes can be<br \/>\nanalysed and comments about the motion of the object can be made.
