Magnetic moment and magnetic properties

AI Thread Summary
Mn+2 has a higher magnetic moment than Fe+2, calculated as √35 versus √25, indicating it is more paramagnetic. However, Fe+2 exhibits ferromagnetism in solid form, making it effectively more magnetic. The ferromagnetic properties of Fe+2 arise from complex interactions between atoms in metallic iron. While Mn+2 is more paramagnetic, Fe+2 produces a stronger magnetic field in solid state due to these interactions. Understanding these differences is crucial in distinguishing between paramagnetic and ferromagnetic behavior.

Homework Statement


Mn+2 has a higher magnetic moment than Fe+2 but practically Fe+2 is ferromagnetic right? So more magnetic right?

Homework Equations


## μ = √ (n(n+1))##[/B]

The Attempt at a Solution


For the Mn ion it comes to be √35 and for the ferrous ion √25
So yes Mn+2 is more paramagnetic but Fe+2 is more magnetic as a solid right?
I really don't know why
Could it be the alligator of the atoms in the solid?
 
Physics news on Phys.org
Metallic solid iron is ferromagnetic and this is a complicated effect involving the interaction of the atoms. It makes no sense to say that ferrous ions are ferromagnetic.
 
Ok Between Fe2+ or Mn2+
Which one produces a stronger magnetic field? Fe2+ right?

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...
