complicates the situation. While smaller extremities like fingers can be easily supplied with a rotating magnetic field, a whole body requires big excitation coils of enormous size. In addition, the optical detection scheme is limited to the penetration depth in human tissues. Even if the detection...

Or, imagine a drive belt with two pulleys. When you turn one pulley, the whole belt moves instantly, and the distant pulley turns too. Yet the belt itself didn't move very fast. The electrons inside the wires are like the circular drive belt. ...
