SMOT stands for Simple Magnetic Toy Overunity. A SMOT consists of two slanting magnetic rails with a track for a steel sphere in between. If the sphere is placed into the magnetic field at the bottom end it rolls along the track.
It is a very easy to replicate experiment that you can try with magnets of different sizes and strengths. If you don't use very strong magnets, this game is even suitable for older pupils (such as the first application in the video).
Part 1: Rolling magnetic rodThe arrangement of magnets - and therefore their polarity - is key for the success of the experiment. In the picture you can see how to position the magnets for the correct polarity. The two rows are not parallel but taper and build a channel. Is is this special arrangement that allows the rod magnet to roll with the two spheres and increase its speed.
Part 2: Sphere in the magnetic channelIn the second SMOT example I placed magnets on the left and right side of the steel sphere. Here it is necessary to use lightly stronger magnets. Attention: It definitely takes a channel of magnets to make the steel sphere go straight. Otherwise it adheres to the nearer magnets.
I used metal profiles on the sides, on which I placed disc magnets S-20-03-N. (Attention: Children should only handle these magnets under adult supervision.)
