If you did build this structure, with the zero field at the center, over a short time the molecules would rotate within the magnetized material.

It is assumed that the molecules are constantly rotating and never get locked into place.

These charges cannot leave the molecules, but the molecules can rotate.

In our physical world, molecules rotate at a very slow rate of speed.

Rosenhaus watched as the molecules rotated toward each other on the screen.

It was thought in the past that the molecules could rotate more or less freely (a 'rotor phase'), so that on a time average they would look like spheres.

At temperatures above 160K the molecules rotate around inside the cage.

The molecule rotates around this sulfur-copper bond.

In addition, small molecules can rotate easily.

A molecule rotates about 1ps per radian in a fluid, thus this loss occurs at about 10 Hz (in the microwave region).
