How do para- and dia- magnetics differ in terms of magnetization?

AI Thread Summary
Para- and dia-magnetics differ primarily in their response to external magnetic fields, with paramagnetic materials being attracted and diamagnetic materials being repelled. The magnetization of a material is influenced by its form, as the geometry can affect the distribution of magnetic domains. The relationship between magnetization (J) and magnetic field strength (H) is described by the susceptibility (χ), which is consistent across different forms of the material. However, the complexity of these interactions suggests that the answer may not be straightforward. Understanding these distinctions is crucial for applications in magnetism and material science.

How does magnetization of a magnetic depend from its form?

Welcome to the PF.

Are you asking how magnets work?

.

I now how magnets work. This question about para- and dia- magnetics. AFAIK \vec J = \chi \vec H and J doesn't depend from magnetic's form. But I have this question in my examination task and I don't think the answer so simple.
 

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...
