I have 4 USB cables with magnets, without their corresponding magnetic USB heads. They have a pogo pin in the middle, just like the ones in the pic, and probably no data transfer (middle pogo pin measures continuity with the +5Vcc pin from the USB plug). The magnets are very strong.
There's a special kind of fun sticking magnets attached to a wire all around the lab, can also be annoying.

Feels like there should be some interesting use for them even without the micro USB heads, but not sure what. Any ideas?
