Knots

I don’t know about you, but I’m using a headphone cord or charging cable, always tied with knots. In fact, such a problem exists and the task of covering a long rope with knots has not yet been completely solved. While there is no formula that would describe the probability of the appearance of knots on a long rope. There are numerical models based on experience, but the theory does not yet exist.

For my part, I want to propose as an idea for realization. Perhaps a magnetic coating, which will always repel, for example, as a magnet holds the cable to the MacBook. Such pots will tend to keep the wire in a straightened state. Yes, and a magnet, as some claim it has useful properties. Wound a wire on a hand, here to you and a magnetic bracelet.
