Solenoid with a magnetic core problem

AI Thread Summary
The discussion revolves around calculating the magnetic field inside a solenoid with a silicon steel core. The user attempted to use the solenoid equation B = μ₀(n)I, adjusting for the core's permeability but arrived at an incorrect result of 4.55. There are inquiries about maximizing the magnetic field from a 2" x 4" core surface and whether any materials can isolate the magnetic field. The conversation emphasizes the importance of correctly applying magnetic field equations and understanding material properties. Overall, the thread highlights challenges in magnetic field calculations and material interactions.

Homework Statement



A long solenoid with 70.0 turns of wire per centimeter carries a current of 0.100 A. The wire that makes up the solenoid is wrapped around a solid core of silicon steel (Km=5200). (The wire of the solenoid is jacketed with an insulator so that none of the current flows into the core.)

For a point inside the core, find the magnitude of the magnetic field B due to the solenoid current.

Homework Equations





The Attempt at a Solution



I used the regular solenoid equation B = munaught(n)I but i replaced munaught with munaught*5200 this gave me 4.55 but that isn't the right answer?

I get the same answer.

BTW, no need to double post. This is the correct forum for this question.
 
Hi:

How can I generate max magnetic field from 2" x 4" core surface?

Any material can isolate magnetic field?

Regards,
Eugene

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}...

Thread 'Struggle to understand the concept of the 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...
