Lorentz-force Memes

Behold, the desperate cry of every physics student who's been handed the Lorentz force equation without proper explanation. The cross product (×) in that equation isn't just mathematical notation—it's the source of existential dread for generations of undergrads. The perpendicularity isn't some arbitrary rule physicists invented to torture students. It's the fundamental nature of how charged particles interact with magnetic fields. When a charged particle moves through a magnetic field, the resulting force acts at right angles to BOTH the field and velocity vectors—creating that circular motion that makes particle accelerators work and compass needles point north. But try explaining that at 3 AM before your electromagnetism final while surviving on energy drinks and despair. Sometimes violence feels like the only reasonable response to Maxwell's equations.

First day of physics: "Just use your right hand to figure out magnetic field directions!" *happy student noises* Two weeks later: "The Lorentz force is given by F = qE + q(v × B) where the cross product determines..." *brain.exe has stopped working* That moment when your professor casually transitions from "wiggle your fingers" to "calculate the electromagnetic force on a charged particle moving through spacetime" is the true university experience. Your confidence evaporates faster than liquid nitrogen at room temperature!
