She argued that teachers' use of control and power over students dulls the students' enthusiasm and teaches obedience to authority, confining each pupil to a role, assembly-line approach to learning.
The domains point in different directions, confining the field lines to microscopic loops between neighboring domains, so the combined fields cancel at a distance.
Various examples exist in particle physics and condensed matter, where certain gauge theories exhibit transitions between confining and deconfining phases.
