And 2 youtubes by (Nick) The Science Asylum (i will show links later). All of these Einsteinian STR explanations for the relativistic cause of magnetism near a wire carrying an electric current are krapp. I will show links & i will point out errors later. --- End quote --- Genuine question, why don't you make response video? --- End quote --- Yes, i think that i could make a number of youtubes, mainly debunking Einstein's famous gedankens, or debunking gedankens like this one by Derek-Veritasium & the 2 by Nick-The Science Asylum. But firstly i think that i would need to bounce my half baked amateur ideas off professionals, eg on this forum. Its funny, the Veritasium youtube claims that the length contraction of the drifting electrons cause of the magnetomotive force is a supreme example & proof of the validity of STR, when my STRIKE-1 post shows that it is a supreme example of a failure of STR. One more catastrophe which might qualify as STRIKE-2. While Veritasium's kitty & The Science Asylum's squirrel are moving along at say 0.03 mm/s in the drifting electron frame, they suffer a repulsion due to the excess of positive charge in the wire, due to the length contraction of the spacing of the protons. What Veritasium & Co failed to tell us is that the kitty & the squirrel were carrying magnetic compasses, & the compasses reacted to the magnetic field, in the same way that they always react, even tho the kitty & squirrel & compasses were moving at 0.03 mm/s. And they failed to tell us that the compasses reacted exactly in that same way (to the magnetic field) at any & every speed (eg -3 mm/s, 00 mm/s, + 3 mm/s)(or at any speed that u might care to nominate). In other words, the kitty & squirrel got (can get) a double dose of magnetomotive force. They get the standard magnetomotive force from the magnetic field (which exists at all velocities), plus they can get the pseudo STR magnetomotive force (which varies with velocity). What a disaster. But there are lots more disasters to follow. |

Regarding the experiment: --- Quote ---Faraday paradox unipolar dynamo demo Part1 38,653 views Aug 27, 2014 plenum88 1.57K subscribers --- End quote --- The experimental setup looks a bit sub-par for one, motor wires running right past the open box of the preamp... not the end of the world, but attention to detail is nice to see. Nothing about the experiment is itself proved, the properties/polarity/field-distribution of the magnet is not demonstrated and the pre-amp isn't demonstrated to be true and linear, if I were more suspicious, I would be wanting to see what the black coax leading from amp to scope was doing off-camera. Of the many more test cases I would want to be seeing, which are unfortunately very difficult to do, a few are: the entire test rig (including scope) rotating, and TBH all permutations and combinations or rotatables in fixed, forward, and reverse; the same combinations repeated with the sliding contacts removed from the surface and also repeated with a fixed short at the ends; and the geometry, spacing, and angle of contact with the disc varied in a few combinations. Eliminating the variables like that does two things, generates more test cases for the proposed theory, and provides more avenues to distinction with competing explanations. --- End quote --- I had a close look at pretty much every Faraday Disc Paradox youtube a couple of years ago, & i think that they all agreed re what did or didn’t happen. I agree with u that there are many variables, but the experiments don’t need to be very exact, they merely need to show which box to tick (rather than provide accurate numbers or something). However i see that Einsteinist's claim that STR ticks them boxes too. I will have to look into that, but i need to deal with Veritasium & Co first. I could have started a separate thread for the Faraday Disc Paradox, but i could see some overlap, which now eludes me today. |

Where did you study Civil Engineering? --- End quote --- I studied in my home town of Ballarat. My average grades were about 51/100, but i got the same salary as the good students. I think that i did Electricity-1 & Electricity-2. And they fed me that krapp about drifting electrons. Little did i know that one day i would discover the true cause of electricity along a wire, ie a new particle, the elekton. |
