Magnetic Field Flux of Neodymium Magnets
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.
