Because Mobius tape has only one side, the length of this side is naturally twice that of ordinary paper rings. Some people think of applying this feature to the transmission belt to spread the wear to more places, thus improving the life of the belt. This idea has also been patented in the United States.
If we imagine the paper tape as a metal tape, and let the current flow in from one clip and out from the other, there may be two directions of current flow on the surface of the paper tape, and the magnetic fields generated by the current in these two directions just cancel each other out. In other words, the current will not generate a magnetic field when the device flows, so there will be no battery induction. This is an inductance-free resistor. This resistance is called Mobius resistance.
Mobius belt is often quoted in artistic and cultural works as a symbol of "infinite cycle":
The international symbol of recycling is a green Mobius belt placed in a triangle. In the cartoon Doraemon (Tinker Bell), there is a Mobius-shaped prop. Just put it on the door handle and the people inside will return to the same room when they open the door.
If we look at the circular sculptures in front of the Science Museum, most of them also use properties similar to Mobius belt. If we have time, we can count how many faces and edges these rings have through these sculptures. I estimate that most of the results are 1. As for the example of escher, it is even more well known, and I don't need to rap.
It is also possible to make Mobius-shaped particles in the laboratory. Not long ago, a group of scientists published a paper in the Journal of Chemical Physics, predicting a Mobius carbon element (specifically graphene) with a shape. It can resist the temperature of about 200 degrees Celsius and is quite stable. Because its Mobius band structure should be a dipole, it can form a stable crystal. Now it's up to scientists to actually make it.
