With this DIY kit, you can discover the fascinating principles of electromagnetic induction and oscillation mechanics in a fun and educational way! Ideal for technology enthusiasts, schoolchildren and anyone who wants to better understand the interaction between electricity and magnetism.
Functional explanation:
The Hall sensor detects magnetic fields and is based on the so-called Hall effect. If a magnet is directly above the sensor, the Hall sensor registers the magnetic field and emits a low signal. This changes the circuit: transistor Q1 is deactivated, while transistor Q2 becomes active.
When Q2 conducts, current flows through the coil L1, creating a magnetic field. The direction of this magnetic field depends on how the current flows through the coil. According to the right-hand rule, this magnetic field repels the magnetic field of the magnet. This pushes the magnet away.
As soon as the magnet is far enough away, the Hall sensor no longer detects a magnetic field and emits a high signal. This deactivates Q2 and the energy stored in the coil is dissipated via diode D1.
This process is constantly repeated, resulting in a continuous oscillation.
