Calculating Magnetic Levitation Strength for a 1kg Object - Physics Forums My initial goal was to determine the devices dimensions and characteristics (including coils electromagnets) stringer than the "usual" devices we see online Unfortunately I was in a hurry (I had to build two devices to levitate a "hoverboard" prop in 6 weeks ) and I ended up using dimensions I found online (look at Nicanor Apostol's work)
Is a Flying Skateboard Possible with Current Technology? - Physics Forums I was just wondering if a flying skateboard would be possible to make in this time and day I don't mean a hover board which uses anti-gravity mechanic, but a flying skateboard which uses a turbojet engine I really want to make one, but I am not sure if it is even possible in the first
