Experiment Smartphones as ammeters
Category Magnetism
Used sensors magnetometer


With the help of this experiment the magnetic sensor of the smartphone can be used as an ammeter for direct current.


Requirements and experimental material

- smartphone (with Phyphox and magnetic sensors)

- a coil (more windings for finer readings)

Introduction

Since the magnetic field induced in a coil by direct current is proportional to the current of the circuit, one can use this to indirectly measure amperage with the magnetic sensor of smartphone.
