For Lucia: was there something that brought you to Canada specifically? And where else would you like to visit in the world?

Well I hope you get the opportunity some time soon, I'm not from the US myself but all of my experiences there have been great

I've got this vague idea for a pet DIY project, a diorama of the old WipEout games. If you're not familiar with the games, it's a racing series centred around these futuristic floating vehicles, which look a bit like this. I found out about diamagnetism, and figured this would be a handy way of getting (small) stuff to float (slightly) above a track. If I was to get two concentric toroidal electromagnets, would a small piece of diagmagnetic material be stable in between the two? And would the field be consistent around the circumference of the toroids?

Edit: lemme know if my explanation sucks and I'll draw a diagram

Yeah, it was diamagnetic stuff I thought would be appropriate, so long as I made them really small and lightweight. Thanks for the article!
