    Magnetic Arrangement Selection

    Thanks, MagBen, I have tried the Halbach array it was fun to learn about and prototype but I found for machining, assembly, and holding the magnets these flat ones with countersink were best. The Halbach array was great though. The 0.7" was selected using Ansys Maxwell about a year ago when I...

    Magnetic Arrangement Selection

    Thanks for the insight. The Br is 14.4 on the magnet website. The dimensions in the steel plate thickness calculator are for the magnet dimensions, not the steel plate. Since I have 4 magnets (1x1x0.25 each) I combined them to be 1 magnet with dimensions of 2x2x0.25in. I combined them all...

    Magnetic Arrangement Selection

    So saturation doesn't necessarily care about surface area, it's more related to the thickness of back shielding? If that is true then your point about removing mass in the center and thickening is very smart. For the thickness of the backplate is there a calculation or anything to find the...

    Magnetic Arrangement Selection

    For some context, this assembly will be mounted under a magnetic wall-climbing car. That is why the assembly weight is crucial for me, it will eat away at my available payload. Thanks

    Magnetic Arrangement Selection

    Thanks for a swift reply @EdStainless! As far as saturation goes on the shielding plate, I think you are right. The weight of the assembly is a constraint for the project, the low as possible assembly weight with the strongest force from 4 magnets. Of course, the curve for the thickness of...

    Magnetic Arrangement Selection

    Hello everyone this is my first post! High-level question about magnet arrangements and which might create a stronger adhesion force. I am using an alternating polarity arrangement because I have tested that to be the strongest. The air gap (ground clearance) between the magnet faces and the...
