Hall Effect: No hall voltage in a Copper sample.

AI Thread Summary
The experiment involves measuring Hall voltage in Bismuth and Copper samples, with expected results from Bismuth but no measurable Hall voltage in Copper, even with increased current. The absence of Hall voltage in Copper may be attributed to its lack of significant Hall effect due to its high carrier density and low mobility. Suggestions for troubleshooting include reviewing the experimental procedure and ensuring proper setup. It is recommended to consult relevant publications that detail the measurement techniques used. Understanding the material properties of Copper is crucial for interpreting the results accurately.

I have been carring out an experiment in which I have to measure the hall voltage in two samples given to me, which are Bismuth and Copper. The Hall voltage values of Bismuth come out as expected but when I measure hall voltage in the copper sample, I do not get any changes in the hall voltage, even when current through the sample is incresed. Why is this this?

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
