FCM Set for Magnetic Fields application



The "FCM", Set for the application of Magnetic Fields, allows the spatial study of the magnetic field in all its dimensions: calculation of magnetic field strength, lines of force, vector potential and equipotential lines, both in static and dynamic fields.

Allgemeine Beschreibung anzeigen



The basis of the "FCM", Set for the Application of Magnetic Fields, is to systematically measure the components of the magnetic field in space. For this purpose, the computer-controlled robot arm sweeps a region of space measuring the intensity of the magnetic field at equidistant points that the student can visualize in real time through the software supplied with the unit.

This unit has been specially designed so that the student can study and experimentally verify laws, theorems and basic principles of magnetism such as: Biot-Savart's law, Ampère's theorem, Lenz's law, the superposition principle, etc., as well as the magnetization effects of magnetic materials: ferromagnetic, paramagnetic and diamagnetic.
