AI Thread Summary
To find the magnetic field (B) and magnetic field intensity (H) along the axis of a uniformly magnetized finite cylinder, two methods can be employed: considering magnetization currents and using the concept of magnetic charges. The discussion raises a comparison between this problem and that of a finite solenoid, questioning their similarities. Magnetic charges are likened to magnetic monopoles, which can be understood through the analogy of electric charges and dielectric polarization. The conversation emphasizes the need for clarity on these concepts to solve the magnetostatics problem effectively. Understanding these methods is crucial for accurate calculations in magnetostatics.

Dear friends,

I'm having trouble with this magnetostatics problem.

I have a uniformely magnetised finite cylinder and I'm asked to find B and H along the axis, using two different methods to get the correct answer.I believe the first one is considering magnetisation currents and the other one "magnetic charges".

I don't know if I'm doing it right when I compare this problem to the one of the finite solenoid (is it the same). What are magnetic charges?

Thanks for your help

I assume "magnetic charges" is referring to the magnetic monolpole. Not sure what you will do with it, but by analogy to electric charges and polarization of dielectrics there should be a representation of magnetic dipoles as combinations of two magnetic monopoles

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
