In this respect, a simple picture of an electric dipole, ⃗ µ, undergoing reorientation in the presence this point corresponds to the null value of the ⃗ µ • ⃗ E scalar product. Eventually, one can not only manipulate the PFCN isomer energies, but also control the relative energy barrier for the switch rotation, i.e., the amount of energy necessary to reverse the motor operation direction.
