Why is the upper magnet in the Stern-Gerlach experiment wedge-shaped?

AI Thread Summary
The wedge-shaped design of the upper magnet in the Stern-Gerlach experiment is crucial for generating an inhomogeneous magnetic field, which is essential for the experiment's purpose of demonstrating quantum spin. The discussion highlights that this design is not arbitrary but fundamental to the experiment's functionality. There is also a side conversation about the categorization of the topic under "Calculus" instead of "Physics," indicating a potential misclassification. The participants agree on the importance of the wedge shape while questioning the relevance of the original categorization. This emphasizes the significance of proper classification in academic discussions.

In the Stern-Gerlach experiment, is there a reason why the upper magnet is wedge-shaped and not flat?


Homework Equations





The Attempt at a Solution

 
Physics news on Phys.org
OK. Maybe that is a silly question. Now that I think about it, the wedge-shape of the upper magnet is the entire point of the experiment because it creates the inhomogenous magnetic field.
 
Exactly!
 
But why, exactly, was it posted under "Calculus" rather than physics?
 
Good point! I didn't even notice that. (I'll move it.)
 

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...
