A3_1 ”Scared Potter?”: The Force of Spells

Abstract

In this paper we investigate the magnitude of the force experienced by a body following an impact from a spell in the Harry Potter film series. After comparing five different spells we determined that the strongest spell was cast by the character Dobby, producing a force of 3600N. Comparing this to the force of a static push, we find that this force is not large enough to propel a human several meters in the real world.
