Field Magnetic Magnetic field Points Solenoid Strength Uniform

AI Thread Summary

The magnetic field inside an ideal solenoid is uniform if the solenoid is infinite in length and the current density is uniform. To understand this, one can apply Ampère's law, which relates the magnetic field to the current flowing through the solenoid. In practical applications, real solenoids may have edge effects that cause variations in the magnetic field strength at the ends. However, for an idealized infinite solenoid, the magnetic field remains constant throughout its interior. Thus, the uniformity of the magnetic field is contingent on these specific conditions.

best answer:

How would you try to figure this out?

simple answer:

Yes, if the solenoid is infinite in length and the current density is uniform. Use the "best answer" to try to figure out why "simple answer" is true. What physical law would you use?

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'

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...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
