Explore the complex motion of charged particles in combined electric and magnetic fields through computational modeling in this 21-minute physics tutorial. Examine exotic particle trajectories that occur when uniform electric and magnetic fields are perpendicular to each other, specifically analyzing scenarios where the magnetic field points in the ŷ-direction and the electric field points in the z-direction. Work through three distinct initial velocity conditions: v(0) = (E/B) ŷ, v(0) = E/2B ŷ, and v(0) = E/B(ẑ + ŷ), to understand how different starting conditions affect particle paths. Use Python programming with GlowScript to visualize and simulate these electromagnetic phenomena, building upon concepts from Griffiths Chapter 5. Develop practical skills in computational physics while deepening your understanding of electrodynamics through hands-on modeling of charged particle motion in crossed electric and magnetic fields.
