Magnetic Circuits, Air Gaps (conceptual)

AI Thread Summary
In magnetic circuits, if fringing is ignored, the flux density in the air gap equals that in the core, indicating uniformity in flux density across the circuit. The flux remains consistent throughout the series circuit, while variations occur in the permeability of different materials and the magnetizing force. This principle is supported by worked examples from provided resources. Understanding these concepts is crucial for analyzing magnetic circuits effectively. The discussion emphasizes the importance of these relationships in practical applications.

Homework Statement


When dealing with magnetic circuits, if the question explicitly states to ignore fringing, then the flux density of the gap will equal the flux density of the core, correct? In fact, if there are ever more materials, the flux density throughout the entire circuit (series) will have the same flux, and flux density. The only thing that will vary is the permeability of each material as well as the magnetizing force, correct?

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}...
