Lorentz Force & Magnetic Ampere Force
安培力与洛伦兹力公式
Theoretical Identity Description:
Magnetic force on a current-carrying conductor (Ampere) and on a moving charged particle (Lorentz). Lorentz force acts as centripetal force resulting in circular orbit radius r = mv/(qB).
Rigorous Derivation Tree
Foundational identity statement defined under standard mathematical conditions.
Targeted algebraic evaluation and parameter substitution.
CSCA Exam Triggers & Traps
Use for mass spectrometers, cyclotron accelerators, and velocity selectors.
Lorentz force never does work (W = 0) because force is always strictly perpendicular to instantaneous velocity.
