> [!cite] [Hysteresis - Wikipedia](https://en.wikipedia.org/wiki/Hysteresis)
> **Hysteresis** is the dependence of the state of a system on its history.
> For example, a [magnet](https://en.wikipedia.org/wiki/Magnet "Magnet")
> may have more than one possible
> [magnetic moment](https://en.wikipedia.org/wiki/Magnetic_moment "Magnetic moment")
> in a given [magnetic field](https://en.wikipedia.org/wiki/Magnetic_field "Magnetic field"),
> depending on how the field changed in the past.
> Such a system is called **hysteretic**.

### Set Notation Example

Let $A$ and $B$ be sets
sharing some but not all elements.

* $A \cap B \neq \varnothing$:
    "The intersection of $A$ and $B$ is nonempty"
    (They share at least one element).

* $A \not\subseteq B$:
    "$A$ is not a subset of $B$"
    ($A$ has at least one element not in $B$).
    Equivalent to $A \setminus B \neq \varnothing$.

* $B \not\subseteq A$:
    "$B$ is not a subset of $A$"
    ($B$ has at least one element not in $A$).
    Equivalent to $B \setminus A \neq \varnothing$.
