I’ve searched but can’t find an expanation i understand. How does the poles (North& South) work on a humbucker magnet? I’ve always thought one half and short end was N and one S. But to get the out of phase tone you rotate the magnet 180 degrees wich would still make the short ends face the same direction. Is N and S on the long flat sides and not the short ends on a humbucker bar magnet? Please an easy explanation!
