'''Ferroelectricity''' is a something some materials, usually [[crystal]]s, do. Ferroelectricity is when a thing has a positive electric charge on one end and a negative charge on the other end, and these charges can switch places if the thing is placed in an [[electric field]].<ref>{{Cite book|url=https://books.google.com/books?id=7yFWuc_YL3UC&q=ferroelectricity&pg=PA5|title=Solid State Physics|date=1957-01-01|publisher=Academic Press|isbn=978-0-08-086468-6|language=en}}</ref><ref name=SD>{{cite web|url=https://www.sciencedirect.com/topics/materials-science/ferroelectricity|publisher=Science Direct|access-date=May 8, 2021|title=Ferroelectricity}}</ref> == Uses == People make [[capacitors|things that store energy]] out of ferroelectric materials. == References == {{reflist}} {{science-stub}} [[Category:Electromagnetism]]
