Looking for information on piezomagnetic materials

AI Thread Summary
The discussion focuses on piezomagnetic materials and their field strengths. Initial confusion arose regarding piezoelectric versus piezomagnetic properties, but the inquiry specifically pertains to the latter. Participants shared resources, including Wikipedia and academic papers, to aid in understanding piezomagnetism. One user noted a journal article that examined the scalar coefficient influenced by field intensity during poling, though specific field strengths were not clearly defined. The conversation encourages further exploration of available literature on piezomagnetic materials.

Could someone help me understand the strength of fields that can be produced with piezomagnetism?

I have not had much luck with searches for these materials.
 
Physics news on Phys.org
lostminty, welcome to Physics Forums. I am pretty sure you are asking about Piezoelectric materials and not “piezomagnetism”. If so, a quick Google search brought me these two sites:

This first one describes the basic science of piezoelectricity. If you compress the material it will generate a voltage, or if you apply a voltage it will expand or contract. See: http://www.piezomaterials.com/

This wikipedia site is detailed and an excellent source for you to study: http://en.wikipedia.org/wiki/Piezoelectricity

If you have further questions or doubts post them here. Google and Wikipedia are your friends…learn to use them to help you learn new things. Good luck!
 
Hi, no I am definitely asking about piezomagnetic materials

http://en.wikipedia.org/wiki/Piezomagnetism

They seem pretty recent, I've looked up articles from my uni's search engine. There is a lot of study with piezoelectric/piezomagnetic composites.
 
Excuse me. Thanks for the new news! I will study up whatever I can find!
 
I found one journal article where they were measuring the scalar coefficient, it was highly affected by what I think was the field intensity during poling. It wasn't clear to me what kind of field strengths were being produced. Might try finding it again...or if i could find the equation for coefficients that would be good.
 
It may be shown from the equations of electromagnetism, by James Clerk Maxwell in the 1860’s, that the speed of light in the vacuum of free space is related to electric permittivity (ϵ) and magnetic permeability (μ) by the equation: c=1/√( μ ϵ ) . This value is a constant for the vacuum of free space and is independent of the motion of the observer. It was this fact, in part, that led Albert Einstein to Special Relativity.
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...
