I Electromagnet Levitation, stationary hoverboard - How?

  1. Mar 16, 2017 #1
    I am University Student currently working on a project to make a stationary hover board. This is just a prototype and does not need to support a human and only needs to support about 1kg but with as much "lift" or distance between the magnets as possible - (100mm?)

    Ideally we want to be able to control the hover board by varying the magnetism of each magnet and so initially we have tested electromagnets (http://www.ebay.co.uk/itm/12V-DC-Su...hash=item23662f9783:m:m8e-RjEY1odRj8cJupM1ymg) and although the attraction force was very strong they did not repel well at all- about 4mm.

    We then tried 25x25mm Neodymium magnets with much better results (70mm lift) but we don't know how to vary or control the magnetism to control the hover board. We want to use an Arduino to make the board move on its own hence the initial thought of using electromagnets.

    Any help would be much appreciated!

    Magnetic forces diminish rapidly with distance. Is there a specific reason want you can't achieve your goals with 4 mm lift?
