Penny is a machine, her "entity" includes ALL of her, including her "strings". This makes for a rather obvious question... what happens when your own aura attacks your own aura?

The most likely answer is this: the greater force wins... and since you are the force on both sides of the equation, you lose. In other words, Penny Nullified her own aura.

The second possibility is that in the above situation her aura never manifests at all, because she essentially attacked herself and her aura treats that just like muscle movement, leaving the tensile strength of the string vs. her body's natural defenses with no input from aura.

The second would be a design flaw, but it would be far from a horrible one, the likelihood of an opponent using magnetism/telekinesis is rather low, especially if this unit was made to mainly hunt Grimm, which supposedly have no such abilities.
