Homework Statement


Does the number of attached identical magnets linearly relate to the number of paper clips/bolts/nuts that are magnetically chained together?


Homework Equations


I have no idea.


The Attempt at a Solution


Yes they are linearly related?

I am guessing that yes it is linear. But I need equations and a full explanation on why this is. Please help!

huh? I don't understand your question. Can you show a diagram?

that's all i am given. there is no diagram or anything...

ok i think i sort of understand what this question is asking. it is saying, if there are more magnets attached to each other, will there be proportionately more papersclips that will attract to the magnets? basically like... how does stacking a bunch of magnets increase the strength of them? provide equations and such

For ferromagnets, we assume the magnetization is linear with field:

\vec M = \chi_m \vec H

So for ferromagnets, yes they are linearly related.
 
Hello everyone, I’m considering a point charge q that oscillates harmonically about the origin along the z-axis, e.g. $$z_{q}(t)= A\sin(wt)$$ In a strongly simplified / quasi-instantaneous approximation I ignore retardation and take the electric field at the position ##r=(x,y,z)## simply to be the “Coulomb field at the charge’s instantaneous position”: $$E(r,t)=\frac{q}{4\pi\varepsilon_{0}}\frac{r-r_{q}(t)}{||r-r_{q}(t)||^{3}}$$ with $$r_{q}(t)=(0,0,z_{q}(t))$$ (I’m aware this isn’t...
Hi, I had an exam and I completely messed up a problem. Especially one part which was necessary for the rest of the problem. Basically, I have a wormhole metric: $$(ds)^2 = -(dt)^2 + (dr)^2 + (r^2 + b^2)( (d\theta)^2 + sin^2 \theta (d\phi)^2 )$$ Where ##b=1## with an orbit only in the equatorial plane. We also know from the question that the orbit must satisfy this relationship: $$\varepsilon = \frac{1}{2} (\frac{dr}{d\tau})^2 + V_{eff}(r)$$ Ultimately, I was tasked to find the initial...
