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 T is a very strong field (the strongest permanent magnet is only ~5 T)

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