   I'm sorry I'm having trouble replying to my own post and those of other   
   writers in this news group using Google groups.   
      
   My thinking tends toward rather divergent novel posts anyway which are   
   difficult to relate to previous posts so it's not a total loss of advantage.   
      
   Today I have a significant development to report in my efforts to construct   
   a homopolar bicycle hub suitable for deceleration, theft resistance,   
   potential energy capture, and limited maneuvering assistance such as   
   driving the outside wheel in a very sharp turn on tough terrain, and   
   backing a tricycle up which is a feature that almost no tricycles have and   
   I mean human power tricycles here human electric hybrid tricycles.   
      
   So that said the homopolar makes use of the generator term in the faradays   
   law I stated in my other post on Maxwell's equations and faradays law. The   
   generator term is the positive term in the sum for e the electric motive   
   force. The alternator term is the negative term in that sum.   
      
   Well I've been tinkering with a small machine tool using a plastic chuck   
   called the unimant one. I've owned one since 1987. I've gripped a small   
   ring magnet made of neodymium iron boron alloy in the three jaw chuck on my   
   machines tiny headstock which is separable from the rest of the machinery.   
   Then what happened that is the development is this:   
      
   I had been toying with the idea of using a plastic core armature to measure   
   voltage induced by spinning the magnet rapidly with the driver motor from   
   the unimat. I gave up that idea. I ordered an inductor stock from Digi key   
   and it has a ferret core which is fairly strongly attracted by the magnet   
   on the chuck.   
      
   Well what happened today is I realized that if I insert plastic sheet or   
   washers between the magnet and the ferrite inductor I can establish a   
   uniform gap with variable friction and explore and plot and that is the   
   crucial part of many scientific and diverse, plot out the relationship   
   between the gap and a limiting current plotted on the y dependent axis   
   which would be the current at which the things stops being stalled assuming   
   that I can get any motion at all and that the heat does not melt the   
   plastic.   
      
   So I really wanted to share this with you all in case I need one has   
   explored homopolar motors in the physics lab. One vendor and I believe they   
   are in Czechoslovakia provides a homopolar motor disproof kit which   
   establishes that no EMF is generated even when the magnets rotate. I don't   
   have that kit so I can't report on the null result.   
      
   A fully developed homopolar bicycle hub motor would have North Pole facing   
   North Pole with a gap between, and an armature wound with a toroidal form   
   having some turns of wire, the core of the armature being a soft magnetic   
   material. Other components made of soft magnetic material would complete   
   the magnetic circuit and ferrofluid can be added to increase that   
   completion effect. In I am nowhere near there.   
      
   But I am making progress and I do like to report progress.
