Mostly Permanent Magnet Motor with minimal Input Power

This plastic closet lock serves three purposes: One, it clamps the magnet array tight from the sides; Two, it protects the array from collision, and three acts as a frame for attachment. This Halbach array 'H" bridge limit switch oscillator should be ten times Art Porter's GAP COP.

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!

The dirty 13, finally showed up: These 13 3/4" N52 magnets were half the price from Magnets4less then K&M at around $100.

Time off for some King Salmon fishing on my 32' Coronado Sloop off the North Coast of California:
