YouTube is your friend (with music)! CLick here. Interesting point. I think the diagram captures the main effect – the re-routing of... -

I think that having (a) as the answer is based on the idea that the atomic orbitals in diamagnetic copper orient themselves to exclude...

I think you are right, and the correct answer is d. A copper shield can be better than a steel shield against a high-frequency magnetic...

IMO the answer-key is wrong and the correct answer is d - the steel sheet. Steel* has a high magnetic permeability. A large steel sheet...

I will rephrase the question. Which of the four materials exhibits stronger diamagnetism? A superconducting sheet would work even better.

Can you post a link to the online question? Obviously any magnetic shielding effect would require a ferrous material.

Ssongoku reacted to Steve4Physics's post in the thread Correct statement about size of wire to produce larger extension with Like.
Here's one way to look at it... For a given material, there is a unique maximum value of strain, ##\epsilon_{max}##, at which fracture...

That relation only holds if, when the force is removed, the wire returns to it's former length. If you apply enough force the wire will...

Sometimes one has to read the whole problem, start to finish. That is the correct way to initially address the problem. So the answer...

Yes, same strain with longer wire means greater elongation. Take note of two things about your first attempt: you made an assumption...
