How does the Lexus hoverboard actually work? A scientist explains

Marty McFly wouldn’t be surprised. Lexus recently announced it had fulfilled the dreams of Back to the Future Part II fans everywhere by building a working hoverboard. And just in time for the October 2015 date that Marty visits in the film to discover kids have ditched skateboards in favour of their flying counterparts.

The Lexus “Slide” hoverboard isn’t set to go on sale but a prototype was recently put through its paces by pro-skateboarder Ross Mcgouran at a custom-built skate park in Barcelona. Now Lexus has also revealed how the device actually works, involving a special track that enables the board to magnetically levitate above it, in a very similar way to maglev trains.

It’s an amusing coincidence that, while Back to the Future featured technology called a flux capacitor, the Slide relies on something called flux pinning, as well as a principle called the Meissner effect. And this all works because of something called superconduction.
