We want 50-50 pieces of them for the first batch. Let me share the meassure feature, we want the magnetic field as strong as you can make it. Let´s make two propolsals for a different material and thickness.
For the first one we need a neodimium magnet with 3 and 5 mm on the thickness, the plates must be must at 30 X 30 cm of lenght and width.
We need one more scope for any Iron ally you may have at your production on tghe run. It could be Boro, Niquel or Cobalto.
Kindly Regards.
