Since discovering the Halbach array I have been thinking a lot about magnetic levitation.
Well actually, I’ve been thinking about magnetic levitation for years. I mean, who in their right mind wouldn’t want to think about magnetic levitation?
But in particular, the Halbach array is a shiny new toy that suggests all sorts of interesting approaches to magnetic levitation. To my surprise, as I have been reading about this stuff on-line, only some of those approaches seem to have been explored.
I may need to write more about this!
Might I suggest electromagnets and thin metal-dipped gloves with a projected display to create a haptic touchscreen?
