Hello there guys.I am currently doing an undergraduate degree in Mechanical Engineering and in order to graduate I have to do a major project by my choosing.So i I chose а magnetic brake, using eddy currents principle.We all saw that cool videos in youtube with magnets and copper tube.So i came up with an idea. As you can see in the attached file, there is a body on which i attached four magnets.Then i put that body between two copper plates.I think its a great idea, the only problem is i`m not so good in that area(lenz`s law, faraday`s law .. etc, etc ). So basically i`m asking for aid. How i can determine with formulas the thin of the plates, the distance needed for maximum slowing effect between the magnets and the copper plates, and what would be the formula for the lenght of the plates. I`m not giving you any details and body`s mass, speed and etc, because you know, after all i need only guideline and i need to use my brain too, from time to time. Thanks in advance!
