This one has been on my bucket list for a while. How to make a Lorentz contraction voltage measurement ? It is my hope by putting some of my failed attempts on the table that others on the list could breath new life into this problem. An out of the box approach from different shoes that would not occur to myself.
First of all what is a Lorentz contraction voltage measurement. If one probe is grounded and the other toughing a magnet the voltage should be extremely negative , 100 KV or so. Not just a magnet but a copper wire carrying 10 amps should also have effective electron contraction leading to an extreme negative voltage around the wire. However it can not be measured with a conventional meter as the meter leads are entering the magnetic frame of reference therefore it cancels out. Its a no win.
Failed attempts on my part. Use a magnetic probe. Close but no cigar as a magnetic probe , current probe , makes a distinction between north and south poles. Lorentz electron length contraction makes no such distinction as both north and south poles have effective length contraction therefore negative charge. Same is true of current in a wire regardless of current direction.
Build a mechanical mono pole south in and another north in with flat magnets then measure the voltage between both opposite mono poles from the inside. Can not remember why I thought that would work. Suffice to say it did not work.
Not tried yet. A gold leaf jar. Replace the gold leaf with two pieces of iron then connect the new iron leaf jar with thin bars of iron to make contact with the magnet. An iron leaf jar would not make a distinction between north or south poles of a magnet as in both cases the iron leafs would separate a little. However would this be measuring a Coulomb force caused by Lorentz electron contraction or just a dirty trick to lose the distinction between a north and south poles?
One more that came from a member on this list to measure sky charge. Sky charge is about 100 volts per meter or 200 volts from head to toe. Like the Lorentz electron contraction this is a voltage that can not be measured with a conventional meter. The solution is a voltage field meter. It consist of a fan , sheet of copper and a hole on top. If there is a fluctuating voltage at the copper plate that equals the frequency of the fan blades than there is an electric field. Maybe this would work?
Any thoughts on this would be welcome.
