Teaching opportunities in measurements of magnetic field

摘要

The measurement of magnetic fields is a complex activity, which can be of significant didactical value. The interference of the numerous sources of magnetic field around the measuring site requires a deep understanding of the fundaments of electronic instrumentation and the particularities of the measurement of magnetic fields. The proposed experimental set-up, which makes use of a 3-axes magnetometer controlled from an Arduino board, also gives the students the chance to practice embedded programming.
