Query: Preisach images of a simple mechanical system   This work is an an early stage of a larger project aiming at answering the
question whether or not the Preisach map is really fingerprinting magnetic
materials. More precisely, we are interested whether Preisach model of magnetic
hysteresis indeed contains any physics or is just a convenient modeling tool.
To this extent we study a very simple mechanical system, thus fully tractable,
subjected to the external force. Despite of its simplicity, our model captures
all the fundamental features of real magnetic materials, namely their
hysteretic behavior, coercivity, remanent magnetization and saturation at high
fields. Both the overall shape of major hysteresis loop as well as First Order
Reversal Curves (FORC's) are reproduced quite correctly; they are very similar
to those observed in magnetic materials. The model essentially consists of a
single, spring loaded, rigid and rotative bar with non-zero friction torque.
The length of a projection of this bar onto the direction of an external force
is identified with magnetization. The friction torque and the spring constant
are the only freely adjustable parameters of our model. Here we investigate,
and present, their influence on the inferred Preisach maps.
