Developing the Force on a moving charge

Developing the Force on a moving charge . April 20, 2011. The equation. |F| = |q| v B sin ( φ ) F = | q| v x B For the direction, you use the left-hand rule (for negative particles) or the right-hand rule (for positive particles) The SI unit of the B -field is tesla [T] = V s m -2

  1. Developing the Force on a moving charge April 20, 2011

  2. The equation • |F| = |q| v B sin (φ) • F = |q|v x B • For the direction, you use the left-hand rule (for negative particles) or the right-hand rule (for positive particles) • The SI unit of the B-field is tesla [T] = V s m-2 • 1 T is a very strong field (the strongest permanent magnet is only ~5 T)

  3. “The cross-product is weird.”

  4. Nikola Tesla, Mad Scientist Some of Tesla’s inventions Alternating current (AC) Induction Motor Wireless Energy Transmission (Tesla Effect) Radio (before Marconi) (His eyes follow you)

  5. Not Nikola Tesla • The Tesla Roadster, an all electric sports car

  6. Magnetohydrodynamics (MHD)
