AI Thread Summary
A discussion revolves around a scientist who, while demonstrating electricity, encountered unexpected results when using a magnet, leading him to dismiss the anomaly as a calculation error. This incident highlights that if he had investigated further, electromagnetism might have been discovered sooner. Participants speculate on the identity of this scientist, with suggestions including Gian Domenico Romagnosi and Andrew Crosse. However, definitive references to the story remain elusive. The conversation emphasizes the importance of inquiry in scientific discovery.

In one of my old physics textbooks, there was a story about a scientist who was demonstrating electricity when it was a pretty new discovery. He had some sort of electrical device that he was showing and at one point he had it near a magnet. It didn't work as expected because of the magnet. The guy dismissed this as something being wrong in the calculations because the relationship between magnets and electricity had not yet been discovered. If he had inquired as to why this was happening instead of just assuming that his calculations had an error, electromagnetism would have been discovered earlier.

I've been googling around trying to find out who this guy was and find some reference to this story, but no luck. Does anybody know?

Hi meni,try googling Gian Domenico Romagnosi
 
Thread 'Griffith, Electrodynamics, 4th Edition, Example 4.8. (Second part)'
I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8. I want to understand some issues more correctly. It's a little bit difficult to understand now. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. In the page 196, in the first paragraph, the author argues as follows ...
Thread 'Inducing EMF Through a Coil: Understanding Flux'
Thank you for reading my post. I can understand why a change in magnetic flux through a conducting surface would induce an emf, but how does this work when inducing an emf through a coil? How does the flux through the empty space between the wires have an effect on the electrons in the wire itself? In the image below is a coil with a magnetic field going through the space between the wires but not necessarily through the wires themselves. Thank you.
