Inductive breaking and AC motors

Inductive breaking used a fixed field and moving conductor.
Faraday laws = battery produced and current made.
Conservation of energy means that the train slows down.
Lenz's law means that resisting and drag soleinoids are made.
In a Tangara the drive motor is shorted over resistors in the roof.
The wheels are connected to gears that drive the motor at high speed.
Wires in the shaft winding carry current, due to the Faraday's Law.
The current creates a drag force due to the

About Me

My photo
I come from a Science family: My father Geoffrey Hill was Australia's first computer programmer on CSIRAC the fourth computer in the world. He is credited with invention of Computer music and the development of “Interprogram” a language before Basic. My PhD is in Atomic and Molecular Physics. I have researched the activated oxygen layer above the ozone layer, and 'Assigned' the world's smallest molecule. At the University of Toronto I researched high power UV lasers. I have specialized in automation in fibre optics. This developed into research in Machine Intellect and Robots. I have enjoyed work as an Explainer with Questacon and my time as a part-time soldier. I currently teach High School Science at Epping Boys’ High.
