This is a response to request by RJBeery in post #102 here: http://www.sciforums.com/showthread...from-a-crank&p=3057051&viewfull=1#post3057051 Concerning a highly controversial claim and apparent experimental confirmation shown in the YouTube vid here: http://www.youtube.com/watch?feature=player_embedded&v=9YHOl7OyfsY A wager of $50 between him and myself was entered into over the course of entries #84-#87 in that thread, and further details ironed out as subsequently shown in the posts leading up to #102 there. Basically, I maintain, based on validity of Ampere's law, no difference in magnetic field will be noticed if one substitutes the sphere with a length of straight wire. Subject to details laid out in above listed thread entries. RJBeery harbors sufficient doubt and agrees to experimentally test this according to already agreed upon protocols. So now I look forward to a list of supplies being furnished.
