I will be talking to a man I know that manufactures magnets, about the potential losses or gains in using different mounting materials and possible benefits of slot mounting etc, they don't let him out much, he's on holiday taking in the sites of several magnet conventions, He's all about magnets, they are his passion ! I may have also sourced an affordable priced supplier for these Type N50 at 50mm x 25mm x 10mm, I've not placed any orders as yet. Watch this space.
Thank you sspence for reminding us, I've taken on board exactly what you have stated, but just on an academic level surely the magnetic lines of flux travel through air space anyway and arrange themselves accordingly , I remember as a child that putting a metal bar across the end of a horseshoe magnet which if memory serves effectively shorts the magnetic field. as I say this is just an academic aspect and hopefully a discussion
Thank you for such a prompt response, I am looking to create such a setup as we have discussed, I intend to simply stack these with the magnets mounted in slots, while I'm at it I will be using other metals and will report on / see what occurs, I may use other prime movers as opposed to simply wind power as you have mentioned in a previous posting, this is of course when I can obtain an affordable source of the Neodymium magnets specified, I'm looking at metric 50mm x 25mm x 10mm, these being respectively smaller by the following sizes of 2mm x 0.4mm x 2.5mm-ish smaller than your 2 "x 1"x 1/2". I do not expect this will create any issues.,I do like this scalable setup and again thank you for bringing it to our attention.
PLEASE ADVISEI've read almost all the replys (there are so many) but I noticed that no one has considered using alternative materials to mount the magnets onto, are you aware of any issues regarding having them mounted onto steel plates and the potential losses that this may create, also what if they were mounted in slots so that the faces in say a stacked 3 (magnetic) plate system, (the middle plate being mounted in slots and having 2 sets of coil resin discs in between them thus making it a total of 5 layers) so that both sides of the center plate provide the magnetic field thus providing potentially a more efficient system?
