    Electromagnetic Induction

    To save money, time and hair, I decided I am going to do all the homework I didn't do at high school and HIT now. These I found were pretty good, or plain fun. Faraday, Lenz, Induction Video lectures (physics, very good elementary stuff with demo's) * MIT Physics II by Walter Levin, lectures...

    Electromagnetic Induction

    Just before going out for the usual 3 hour bike ride, heavy downpour started so now I'm stuck inside. julesa - Yes I could, well, or just get a hub-dynamo. But I want something that I can easily build (no shop). I think bicycle wheel is strangely unexplored in its electromagnetic properties...

    Electromagnetic Induction

    liveforphysics - that disk brake -type structure is very good idea. Close to the axle 3-5 mm tolerance is a lot. I wasn't quite sure why you mentioned the Agni axial flux-gap motors, or what it was - so I ended up reading this...

    Reid Welch - What a beautiful piece of work! And to ramble a bit, yes, I can relate to your words about 'noob basics'. :oops: I am so there, despite physics, electronics and circuit design courses. Ah well, one day I hope I will understand reality. On topic of brushless/induction dynamo: To me...

    Electromagnetic Induction

    Ah, thanks to the instructables -page below, I now have found an inexpensive source of magnets - used hard-drives. I think these should be easy to come by in quantity. fechter - Thanks for the Welcome. 8) Just now I am trying to figure out a way in my head to 'temporarily magnetise' just the...

    Electromagnetic Induction

    Good Planetary Day Everyone, I hope this thread will serve as a platform and reference for actualizing a simple inexpensive diy induction dynamo, and 'motorless' assist and EM-brake. First, let me introduce myself, feel free skip to next paragraph for on-topic. I'm Casimir and after...
