Charms Homework
Every charm has been an experimental charm at some point in history, and was invented to fulfill a need by society. Before Ministry regulations came into effect, charm inventors spent their lives theorizing, inventing, and perfecting their many charms and relied on trial-and-error practices that, at many times, resulted in deaths or injuries. While there were many who sought to invent charms for their own needs and purposes, the advanced skills required to do so made it nearly impossible for any witch or wizard without the proper education and training.

The question of why so many charms came about is still a subject of great debate among the academic community, but some of them have clearer answers than others. For example, the patronus charm - a powerful defensive spell, but a charm nevertheless - was likely created to ward off an influx of dementors, while the muggle-repelling charm was created to ward off muggles. The Committee for Experimental Charms now evaluates charms based on their own criteria to ensure that no one is able to create their own spells for nefarious purposes. As such, it is rare for a new charm to come about without the public being informed.
