The discussion revolves around the concept of current induced in a wire loop by a magnetic monopole passing through it. Participants explore the implications of a hypothetical magnetic monopole's magnetic field and its effects on induced current, referencing Faraday's law and the characteristics of magnetic fields.
The discussion is active, with participants offering hints and references to external resources. There are differing interpretations of how the magnetic monopole's motion affects the induced current, and some participants express confusion about the setup. A participant acknowledges a misunderstanding, indicating a progression in their understanding.
There is an emphasis on the constraints of the problem being a multiple choice question, and participants are encouraged to analyze the answer choices critically. The discussion also highlights the importance of understanding the behavior of magnetic fields in relation to induced currents.
The B field would look like this:hutchphd said:
Motion of the particle is not symmetric and flux is zero only when particle is centered exactly in loop. Look again.versine said:
I disagree. If normal bar magnet passes through the loop, the current rises, goes to zero, then reverses direction. If a magnetic monopole passes through the loop the current rises but never returns to zero (barring resistive dissapation). Can you see why? For an explanation please read the link in my post #3.versine said:
