This paper reports on the result of a research into the utilisation of a smartphone for the study of
magnetostatics on the basis of experiments. The use of such a device gives great measurement result
and thus it can replace magnetic sensor tools that are relatively expensive. For the best
experimental result, firstly the position of the magnetic sensor in the smartphone has to be
considered by way of value mapping of a magnetic field due to permanent magnet. The magnetostatics
experiment investigated in this research was the measurement of magnetic field due to electrical
currents in two shapes of wire, straight and looped. The current flow, the distance between the
observation point and the wire, and the diameter of the loop were the variable parameters
investigated to test the smartphone’s capabilities as a measurement tool. To evaluate the
experimental results, the measured data were compared with theoretical values that were calculated
by using both an analytical and a nume…
