Development of a Metal Detector for Smartphones and Its Use in the Teaching Laboratory
Sobral, Geraldo A.
Physics Education, v53 n4 Article 045006 Jul 2018
In this article, we describe how to develop an inductive metal detector that can be integrated to any Android or iOS smartphone with a standard audio port at low cost. The results indicate the metal detector can be used in the physics teaching laboratory as a practical application of principles of electromagnetism. It allows one to differentiate ferromagnetic samples from the diamagnetic and paramagnetic ones and can also be used to investigate the direction of alternating magnetic fields and to demonstrate the Faraday's cage shielding effect.
