Study Notes
Lorentz Force: The Left-Hand Rule
- Using the left-hand rule, the direction of the Lorentz force acting on a current-carrying conductor in a magnetic field can be determined.
- Thumb indicates electron movement direction.
- Index finger shows magnetic field direction.
- Middle finger points to the force direction acting on the current-carrying conductor. This is the Lorentz force.
