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.
Contents
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.
