How magnetometer works? | Working of magnetometer in a smartphone | MEMS inside magnetometer

This video tutorial introduces the magnetometer, a device used to detect magnetic fields, and explains its functionality in smartphones. It delves into the Hall effect, a principle where a voltage is generated across a conductor in a magnetic field, and how this principle is applied in Hall effect sensors to measure magnetic fields. The video also covers the changes in electron density and force experienced by charged particles in a magnetic field, leading to potential differences. Finally, it discusses the output of Hall effect sensors and concludes with a call to action for viewers to engage with the content.
