In this Education video tutorial you will learn how to conduct a viscous remanent magnetization (VRM) experiment. The purpose of this experiment is to measure the VRM decay vs time. You have to take two Orbo rotor magnets and mount them on a base. Mount two samples of the ferromagnetic tore used in the Orbo motor for the stator coils on a rotating disk. The disk can be rotated by a simple brushless motor. When the ferromagnetic core moves in front of the static magnet, an optical sensor detects the starting position and sends it to the scope. A moving Hall probe sensor is used to measure the VRM level in the ferromagnetic core along the circumference of the rotating disk. The VRM level is recorded vs the time.
