Magnetic Field Flux of Neodymium Magnets

Click For Summary
SUMMARY

The discussion centers on the magnetic field flux of neodymium magnets, specifically their magnetic flux density, which ranges from 1.0 to 1.4 teslas as per data from Cy-Magnetics. It is established that while intuitively adding more magnets may seem to increase flux density, the actual increase is limited due to magnetic saturation effects. Stacking neodymium magnets beyond a certain point contributes negligibly to the overall flux density, as saturation occurs and the material's inherent properties dictate the maximum flux density achievable.

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.
