Magnetic flux between coaxial conductors

AI Thread Summary
The discussion focuses on calculating the total magnetic flux enclosed within coaxial conductors, with the inner conductor carrying a current I. The magnetic flux density is given by the equation B_(phi)=(mu_0)*I/(2*pi*r). Participants question whether the outer conductor influences the magnetic flux, concluding that it does not affect the magnetic flux density from the inner conductor. The consensus is that the outer conductor merely defines the region for flux calculation without altering the flux itself. Overall, the outer conductor's presence does not change the magnetic flux generated by the inner conductor.

Homework Statement


A coaxial conductor has the length L. The inner conductor of radius a carries a
current I in the z direction. The outer conductor is very thin and has the radius
b. Calculate the total magnetic flux enclosed within the conductors.


Homework Equations


Magnetic flux around a cylindrical conductor: B_(phi)=(mu_0)*I/(2*pi*r)


The Attempt at a Solution



The question really is whether the outer conductor does anything except determine the region where the flux is to be calculated. Is the outer conductor affected at all since the magnetic flux density from the inner conductor isn't changing, and does it then have any effect on the flux?

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging 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...
