  12P04 Moving Charges and Magnetism


What is Lorentz Force?
A current carrying conductor in a magnetic field will experience a Force.
FLH Fleming's Left Hand Rule

Principle of Electric Motor
A current carrying coil in a magnetic field will experience a Torque.
FLH Fleming's Left Hand Rule




DC Motor
What is the Torque formula for a DC motor? Connect that with the parameters given to control the speed of rotation.

What can you say about Motor vs. Generator? Can you think of the Flemings Left Hand Rule and Right Hand Rule to apply it for Motor and Generator?

What is the emf generated formula for AC generator? 
What shape is the curve of emf generated and why?





The Lorentz Force F = q (v x B)
