Magnetic field inside coaxial conductor

AI Thread Summary
The discussion focuses on determining the magnetic field inside a coaxial conductor with an aluminum wire and a surrounding aluminum shell, while considering the presence of oil between the wire and shell. The key point is that the oil's different magnetic permeability must be factored into the calculations, as it can influence both the direction and magnitude of the magnetic field. Participants emphasize the importance of understanding how the oil's properties affect the overall magnetic field behavior in the system. The problem highlights the need for careful analysis when incorporating materials with varying magnetic properties. Accurate calculations are crucial for understanding the magnetic field in this coaxial conductor setup.

Homework Statement



The problem asks us to find the magnetic field inside a coaxial conductor that consists of an aluminum wire of radius r1 surrounded by a cylindrical aluminum shell of inner radius r2 and outer radius r3. I know how to do this, but it also says that there is oil flowing between r1 and r2 to carry away heat. Does this change anything about the direction and/or magnitude of the magnetic field?

the oil will have a different value of magnetic permeability, which you must take into account.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
