As I wave my hand over this mystery rock, it levitates to my hand. But alas, all that is in my hand is a rod and some copper.
What is going on here?!

Good one.
Fun science though not especially challenging. Thanks.
This was good, although a bit too easy, good going and give some more
at first i thought magician then i was like hey wait a minute copper coil magnet??
I first thought it was a magnet (rod, and the rock would be a magnet). But then I realized it wasnt a trick question and the copper actually has to do with something... Then I got stumped 'cause I always thought copper was for making money.
simple....got it in a second...good one too...
albeit easy,the wording is confusing.once the magnetic force is great enough to lift the object the two would conjoin immediately.as well,levitation conotates an open hand.
um... i was totally lost... im not good at science....i guess if you like that kind of stuff it'd be cool... good job anyways...
Pretty easy, but then again I like 'em easy!
Very clever!
The problem here comes when I ask where the battery is. I suppose you might have the copper hooked up to a seperate battery, but holding the bare copper wire in your hand while undergoing enough of an electric current to create sufficient EMF to overcome gravity would be... phenomenal. This in itself would be magic.
1000th teaser!
