What Happens to Materials in a Magnetic Field?

AI Thread Summary
When a material is placed in a magnetic field, it can become magnetized, aligning its atomic or molecular dipole moments. The extent of this magnetization varies depending on the type of material, with ferromagnetic materials like iron exhibiting significant magnetization. This alignment leads to an increase in both internal and external magnetic fields. The effects can be observed on a macroscopic scale, depending on the material's properties. Understanding these interactions is crucial for applications in magnetism and material science.

Just want to know what happen to a material when placed in a magnetic field? and does anything happen the magnetic field

Hi there,

Are you looking for a macroscopic effect on matter? If so, it really depends on the magnetic type of matter.

If you are looking for an atomic explanation, I would be glad to help you, but you need to let me know first.

Cheers
 
The material will become magnetized, which is an alignment of atomic or molecular dipole moments in the material. For iron, this magnetization can be very large.
The magnetization of the material will usually increase the internal and external magnetic fields.
 
Thanks

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
