"An electrotransmissive magnetic field is a magnetic field that electrical currents can pass through. That means I can move my hand and arm and receive feedback from it, even though there are no physical connections between the joints. As you can see, omnic engineering is quite different from human physiology, so our responses to different things will be very different."
