http://scratch.mit.edu/projects/13399200/#fullscreen http://scratch.mit.edu/projects/13162517/#fullscreen It is about the electricity production by generators.This is going to explain how VOLTAGE and CURRENT appears and how their diagram looks like. More importantly is to understand the angle between velocity vector and the magnetic induction vector (V the angular speed of the coil into magnetic field B) You have the option to achieve all modules from 1 to 20 or to choose the ones important for you in order to understand how the electricity is generated. I will encourage you to achieve the complete package and read them step by step as indicated below. Highlighted item is the one you just achieved: Lorenz Force Faraday’s Law
Permanent magnet and the electromotive force(EMF) Moving a coil into a magnetic field The Magnetic Flux Magnetic Flux & Surfaces Magnetic Flux and Voltage Magnetic flux variation How the Electromotive Force will appear Magnetic field intensity (B) Wire polarization with electric charges EMF formula: U=V*B*L*sin θ
