Magnetic Field Flux of Neodymium Magnets

AI Thread Summary
Magnetic flux density for neodymium magnets ranges from 1.0 to 1.4 teslas, but adding more magnets does not necessarily increase the flux density significantly due to saturation effects. The confusion arises from misunderstanding the concept of flux density, which is primarily determined by the material properties rather than the quantity of magnets. Stacking magnets can lead to diminishing returns in flux density as saturation occurs. For effective power generation through magnetic induction, understanding these principles is crucial. Further research on magnetic induction and flux density is recommended for clarity.

Greetings,

I am trying to figure out how I would design something that produces power using magnetic induction, but I think I've confused myself on some of the ideas and terms behind it. I found data on neodymium magnets from http://www.cy-magnetics.com/Mag_Pros_NdFeB.htm and it seems that the magnetic flux density is between 1.0-1.4 teslas. So, what I'm confused about is whether the flux density increases with each magnet you add to the system or if is just a constant based on the material and it doesn't matter how much material you have.

Intuitively it seems that the flux density would increase with more magnets, but I may just not understand what flux density really is. I've been trying to read more about it, but I think I've just confused myself more, so if anyone can set me straight on the matter, or at least point me in the right direction, I would be very grateful.

At some point stacking magnets adds very little to the flux density due to saturation of the magnetic flux.

Thread 'Inducing EMF Through a Coil: Understanding Flux'

Thank you for reading my post. I can understand why a change in magnetic flux through a conducting surface would induce an emf, but how does this work when inducing an emf through a coil? How does the flux through the empty space between the wires have an effect on the electrons in the wire itself? In the image below is a coil with a magnetic field going through the space between the wires but not necessarily through the wires themselves. Thank you.

Thread 'Griffith, Electrodynamics, 4th Edition, Example 4.8. (Second part)'

I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8. I want to understand some issues more correctly. It's a little bit difficult to understand now. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. In the page 196, in the first paragraph, the author argues as follows ...
