The problem involves a coil with a specific number of turns and dimensions, where a magnetic field is applied perpendicularly. The goal is to determine the rate at which the magnetic field must change to induce a certain current in the coil, using the properties of copper and relevant equations.
Participants are actively engaging with the problem, exploring different equations and their applicability. Some have provided calculations and are seeking verification or correction of their methods. There is a recognition of potential errors in previous calculations, and multiple interpretations of the problem setup are being considered.
There is a mention of homework constraints, including limited attempts on an online platform, which adds pressure to find the correct solution. Participants are also clarifying the definitions of variables and their relevance to the problem.

hage567 said:I was referring to the L in the resistivity equation that Bubbles was asking about.
BuBbLeS01 said:How do I find L with having the diameter and number of turns??
BuBbLeS01 said:I was going to find E using I = E/R then use that in the equation...
E = A * B/t to get the rate
BuBbLeS01 said:oh lol...ok so my length is 9.8696 the when I use R = pL/A is it the area of the wire or coil??

hage567 said:The question did not actually state that this was a solenoid. It said it was a loop of 102 turns with a magnetic field perpendicular to it (so going through it). The magnetic field is not being produced by the coil. So I don't think the B = U*I*(N/L) equation is what you are looking for here, IMO.
BuBbLeS01 said:oh noooo I got it wrong! My final answer was 53.6469 T/s
I did it twice but I am still getting the same answer let me show you what I did maybe I missed something...hage567 said:I get a different answer than this. Try checking your math over carefully and see what you get.
