Undergrad Magnetic levitation with permanent magnets
So, i figured that youd like an update on the Leviskate PM, after realising that a radial array of magnets i the configuration i wanted them in was going to cost anywhere from £1500 to £2800 to have made i started to think that it may turn out to be an idea that has zero appeal due to...- Mack7963

Undergrad Magnetic levitation with permanent magnets
to be honest i hadnt, i but with this developing in the way it has i have been playing around with different shapes, with 3d printing so cheap, and the added bonus of the magnetic field that will support the weight will also act like a pillow, in other words, there will be no point that the...- Mack7963

Undergrad Magnetic levitation with permanent magnets
i dont, i didnt design the trucks by the way, they were the closest thing to what i wanted i could find in the time i had, i have a very basic working knowledge of a lot of 3d software but no real skill in any of them, the top board and the bottom bar are the only things i designed from scratch.- Mack7963

Undergrad Magnetic levitation with permanent magnets
as would i if this were designed to be a trick board, taking into account the downward forces generated on landing and the weight of the rider, the magnets would never last past one trick, this is primarily a cruising board, the sogginess of t supportive magnetic field will give a feeling of...- Mack7963

Undergrad Magnetic levitation with permanent magnets
i will take that complement about the design and pay for it with thanks, at this stage its no longer about if it will work or not, now its about getting it to that point where my own eyes see the end result, and above all else its been a learning experience, i know more about magnets now than i...- Mack7963

Undergrad Magnetic levitation with permanent magnets
the only thing i have at the moment are renders of the concept, which i have included in this reply, , as far as the stability of the floating board, i have the vertical lift sorted, i have the rotational aspect sorted and i have the lateral control sorted, as i said in an earlier post, i am...- Mack7963

Undergrad Magnetic levitation with permanent magnets
well, for a start once the lift to weight ratio has been solved the board could support somones weight, with the lateral motion being controlled the person could propel themselves forward in the same way as a conventional board is used, and lastly magnetic fields move in a very similar way to...- Mack7963

Undergrad Magnetic levitation with permanent magnets
your thinking is a little too literal for me, i would have to be an absolute idiot to think i could make something repel away from the earth, but to have something repel away from a different kind of surface such as a skateboard that can have a means of repulsion attached to it isn't the...- Mack7963

if and only if this last part doesn't work, with the dimensions it requires to work, then i will give up and move onto electromagnets :)- Mack7963

Undergrad Magnetic levitation with permanent magnets
yeah I've seen that, but what i figured, especially with magnets is, that if you purposely introduce Newtons third law into the equation, then it let's you approach the problem from a whole new angle- Mack7963

thats what the one step away is, getting quotes to have the magnets needed engineered, the requirements are proving costly- Mack7963

Undergrad Magnetic levitation with permanent magnets
so i am literally one step away from producing a floating skateboard powered by permanent magnets, so here's what i wanted to check, to make sure I haven't missed anything obvious vertical lift achieved by using vertical repelling fields rotational motion is controlled by counterbalancing the...- Mack7963

Undergrad Could Earnshaw be only thinking inside the box
Dale so if the sliding off the field is one of the issues, do you think that if the east west magnets where angled outwards then they would centralize themselves, again going back to each one canceling the other out, if one magnet is pushing against the other both with equal force, then...- Mack7963

Undergrad Could Earnshaw be only thinking inside the box
i get the arguing against math point, trouble is that won't satisfy my sense of logic until i actually see it not working, i believe the other term for this condition is stubbornness, thank you though for the good luck sentiment, i have seen the frog levitation experiment, all i need to do now...- Mack7963
