Hi Everyone, I hope this is ok to post in this section this is my first time on here. I recently was watching a show on maglev trains (I know this is not new technology but I found it really interesting). I love to tinker with little projects in my shop and was wanting to build a gadget to lift using an electromagnet. This is what I had in mind and was hoping for some help to tell me if my thinking is way off or not. From what Ive researched an electromagnet will repel a permanent magnet. I would have two platforms connected on rails to keep them centered. When the electromagnet is energized it would repel the permanent magnet attached to the top platform, thus lifting any weight on top (Picture Below). Thanks any help/suggestions/corrections would be appreciated.
