Abstract

This paper describes the use of an inexpensive smartphone's magnetic sensor to measure magnetic field components (B[subscript x], B[subscript y] and B[subscript z]) induced by current wires in magnetostatic experiments. The variable parameters used to measure the magnetic sensor's capabilities were: the geometrical shapes of the wire, current flow, and the distance between wire and observation point. The experimental results are in good agreement with the results obtained from calculations using an analytical and numerical approach. In addition, the 2D vectors and magnitude of the magnetic field have been successfully illustrated. This study confirmed that the inexpensive smartphone's magnetic sensor had a good ability to accurately measure the components of a magnetic field in a magnetostatic experiment, which is especially suitable for undergraduate students.
