Bloch Wall Resonator Jack Scholze Uploaded on Feb 20, 2011 Mounted a couple of neodymium disk magnets on a vertical shaft, in opposition south-to-south to have a floating bearing setup. The bearings at top/bottom serve to align the shaft, but do not have to bear a load. To spin the shaft Ive put a 1 inch diameter neo-cylinder magnet and drive coil at the top. It runs quietly at about 6000 RPM. The coil needs to be tilted and the Hall sensor adjusted for best performance, RPMs and torque. The disk magnet mounted on the shaft is a small homopolar generator. It produces about 0.4 volts at speed between the edge of the disk and the drive shaft. A very weak generator. The 7 point starship coil on the top is the Scot Nelson Daisy 7 geometry that he discovered. It has the largest FEMC and BEMF Bedini type backspikes I have seen yet on any coil, approx 600 volts, for any of the pulse motors Ive built. This backspike can be used to effectively charge capacitors or batteries, which seem to absorb them well and the charging gets better and faster over many charge and discharge cycles. Se also my Nelson Daisy 7 video for more on this coil. Thanks for watching. youtu.be/v950YJhjz3Q
