Lesson 2: Why do we observe beautiful night sky patterns near the poles?Comparing properties of magnetic (Lorentz) & electric forces
Google ClassroomLet's compare and contrast the electric force and the magnetic force, the Lorentz force, properties. Created by Mahesh Shenoy.

There is a significant error in this video. The speaker says that applying a force perpendicular to the motion of an object cannot change the speed. That is not true. It's true for a very specific reason in the context of magnetism or centripetal force, but in general, if you apply a force perpendicular to the motion of an object it will influence the speed. Imagine if a soccer ball is slowly rolling on the ground and you kick it with a force perpendicular to the direction it was rolling. That will influence the speed of the soccer ball.(1 vote)
