## Hysterese - Wikipedia

Hysterese of hysteresis (Grieks: 'het achterblijven') is het verschijnsel dat het verband tussen oorzaak en gevolg niet alleen afhangt van de grootte van de oorzaak, maar ook van de richting waarin de oorzaak verandert.. Hysterese wordt veroorzaakt doordat een systeem bij dezelfde externe factoren (oorzaak) twee verschillende stabiele toestanden (gevolg) heeft.
