The Magnetic strips you find on discarded Refrigerator's doors: An easy, free, way to get lots of tiny Magnets, so you can build a looong Halbach Array for your Toy Monorail, or anything else! Find the North of that Magnet strip. Paint it, if there's not a groove on it, like in my example. Cut the magnet bars to the same lenght as the Magnet's thickness, you get a square section magnet. Put one then the next, rotated 90 degrees, and so on. you get a Monorail Magnetic Halbach array!
