Used sensors magnetometer


The magnetic sensor is used to display the magnetic field of a coil in a RC circuit.


Requirements and experimental material

- smartphone (with phyphox-app and magnetic sensors)

- a coil with low resistance and high inductance (for more information see paper)

- some capacitors between 470uF and 22.000uF

- a battery or power supply

Introduction

In this experiment a very simple LC circuit is created with a coil and a capacitor. To measure the magnetic field the coil has to have a low resistance and a high inductance. Such coils can be bought in audio supply and can be a bit expensive. The used coils for this experiment can be found at [1] and [2]

Paper, and work sheets

The experiment was developed in a thesis for education students (Staatsexamensarbeit) at the University of Konstanz. The results where published in an open access paper [3], where a lot of additional information can be found.

Work sheets in German where developed and can be found here. TODO
