  • Hallbach array.

    Here's a hybrid Hallbach array from craft sticks and rubber bands:

    • Hallbach array.

      A closet lock acts as a frame and collision bumper for the array stator. This design should be 10 times Art Porter's COP.

      • Prototype

        Ampere's law can calculate the correct amount of amperage to equal the magnet strength with the inductance of the coil. A masking coil can double the strength of it's backing magnet with the equal strength amperage. The Halbach coil "Quintuples" it's equivilent strength when energized. Art Porter needs a masking pulse of opposite polarity to neutralize the attraction. The EM Hallbach projects zero field in the plane of attraction when denergized. So we get 5 times the amplified force and the neutralization for free. That adds up to 10 times Art's COP!

        I just ordered 13 3/4" N52 cubes from K&M to complete the build. I'm back in Northern California, and the magnets should arrive in a few days. The prototype is a just a ""Quick and Dirty" test job that works fantastic and proof worthy for a major scale up, so here goes!

          Magnets4less has the 13 N52 3/4" cubes for half price compared to K&M. I have a tracking number.

              • 1/2 Hallbach array.

                This half a Hallbach array is hard to squeeze into the sides of the EM coil. A strong rubber band is necessary.

                Consider the unique effect as far as the monopole "H" bridge oscillator is concerned; The North pole of the EM is amplified in both directions by a current reversal in the electro magnet!

                  Pressing magnets against the sides of any electro-magnet coil N pole repulsive, should produce the 1/2 Hallbach effect.

                  • 1/2 Hallbach array.

                    Pressing magnets in opposition against the sides of an electro-magnet should work much better then the relay coil. A 100 Newton cylindrical metal Case EM with ceramic magnets powerful enough to repel beyond the attraction to the ferrite.

                        • Pontoon coils

                          The cantilevered EM coils permit the halbach cube to attach squarly to the central keeper with no wire wraps in the way. The Inductance multiplies and the field strength increases proportionally. The EM hybrid would slip sideways into the array and a second transformer stator would attach to the magnets from the other end.

                            This geometry quadruples the force, or quarters the input:

                            • Hallbach MEG

                              The encircled area pictures one output coil of six on the upper "E" stator. There would be six output coils of this type and eight of the two EM cubes one not pictured. Fourteen coils and three powerful permanent magnet cubes:

                              Reversing the current on the "H" core would keep the core de-saturated.
