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

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)
