Magnetic moment and magnetic properties

In summary, the conversation discusses the differences in magnetic properties between Mn+2 and Fe+2 ions. While Mn+2 has a higher magnetic moment, Fe+2 is practically ferromagnetic due to its solid state. Fe+2 also produces a stronger magnetic field compared to Mn+2. The equations used to calculate the magnetic moments for both ions are √35 for Mn+2 and √25 for Fe+2. The complexity of the ferromagnetic effect in solid iron is also mentioned.

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?

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.
 
  • #3
Ok Between Fe2+ or Mn2+
Which one produces a stronger magnetic field? Fe2+ right?
 

FAQ: Magnetic moment and magnetic properties

What is a magnetic moment?

A magnetic moment is a measure of the strength and direction of a material's magnetic field. It is a vector quantity, meaning it has both magnitude and direction, and is typically represented by the symbol μ.

How is magnetic moment related to magnetic properties?

Magnetic moment is a fundamental property of materials that determines their response to magnetic fields. It is directly related to other magnetic properties such as magnetic permeability, susceptibility, and coercivity.

What factors affect the magnetic moment of a material?

The magnetic moment of a material is influenced by its atomic and molecular structure, as well as the external magnetic field it is exposed to. The number of unpaired electrons and the strength of their spin also play a role in determining the magnetic moment.

What is the difference between magnetic moment and magnetic dipole moment?

Magnetic moment refers to the overall strength and direction of a material's magnetic field, while magnetic dipole moment specifically refers to the magnetic field produced by a single magnetic dipole, such as an electron. Magnetic dipole moment is often used to describe the magnetic properties of individual atoms or molecules.

How is magnetic moment measured?

Magnetic moment can be measured using a variety of techniques, such as the vibrating sample magnetometer or the SQUID (Superconducting Quantum Interference Device). These methods involve applying a known magnetic field to the material and measuring the resulting magnetic flux or force, which can then be used to calculate the magnetic moment.
