Viscous Remanent Magnetization Measurement for Steorn Orbo Motor

The purpose of this test is to measure the Viscous Remanent Magnetization decay Vs the time of the toroïdal ferromagnetic core used in the Steorn Orbo motor v4.1. When the 1st rotor magnet lives the toroïdal core, the ferromagnetic material of the core remains temporarily magnetized to the opposite polarity of the leaving magnet due to the VRM effect. So, the 2nd rotor magnet will be more attracted by this temporarily magnetized core during its approach. The time of the VRM decay is very important to get free energy from this process and its tuning is critical… more info at : jnaudin.free.fr
