Magnetic field in the center of the toroid

AI Thread Summary
The discussion centers on calculating the magnetic field at the center of a toroid using the formula B = mu*N*I/2*pi*r. However, the book states this approach is invalid due to the lack of a constant field path through the center. Participants suggest using the Biot-Savart Law as an alternative method for this calculation. Guidance is requested on how to effectively apply the Biot-Savart Law in this context. The conversation emphasizes the complexities of magnetic field calculations in toroidal structures.

Can't this be calculated from B = mu*N*I/2*pi*r? Book explanation says that this can't be done because there is "no path through the center along which the field is constant" So I guess I must use the Biot-Savart Law. How should I go about doing that?

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}...
TL;DR Summary: Find Electric field due to charges between 2 parallel infinite planes using Gauss law at any point Here's the diagram. We have a uniform p (rho) density of charges between 2 infinite planes in the cartesian coordinates system. I used a cube of thickness a that spans from z=-a/2 to z=a/2 as a Gaussian surface, each side of the cube has area A. I know that the field depends only on z since there is translational invariance in x and y directions because the planes are...
