1. A data storage apparatus comprising:
a well structure comprising a suspension medium having a material state comprising an alterable viscosity property or an alterable material phase property providing selectable mobility of a magnetic particle within the well structure;
the magnetic particle disposed in at least a portion of the well structure; and
a control system configured to represent a data state corresponding to a positioning of the magnetic particle within the well structure, the magnetic particle moved responsive to an applied field and a present material state of the suspension medium.
