This toy is made by Carlisle Co., Mound House NV. US Patent #5182533. Made in China. It is a magnetic levitation bearing that spins for a long time with only a metal point touching the glass on the left. There are four magnets in the base and two in the axle.

The classic Wheelo Junior toy


I received this toy as a small child from my grandfather. It has a plastic wheel on a magnetic steel axle. The wheel spins and runs around the inside and outside of the wire track as you move the track up and down. It makes a neat noise when you get it going fast. This toy was made in the 1950's or 1960's. Various copies are still sold today. Out of patent.
