SUMMARY
Electrets are materials that maintain a quasi-permanent electric charge. They can indeed be used to electrostatically charge metal plates, functioning similarly to how a glass rod attracts paper pieces after being rubbed with wool. The discussion highlights the importance of understanding different types of electrets and their applications, as outlined in the provided Wikipedia links.
