A detainee would hover over a meter, held inside the blue-colored field, and be required to wear magnetic cuffs that not only anchored the being in place but also monitored life signs, since a too-powerful field could stop one's heart or cause irreversible brain damage. In addition, the cuffs could be used as torture devices, capable of unleashing powerful electrical charges, and rotate the prisoner. Against Jedi, the field served to disrupt the captive's connection to the Force, preventing their escape.
