Yup, like water. Diamagnetic stuff is repelled out of regions of strong magnetic field and so it can be levitated if you can make the field strong enough. Frog is mostly water. Here is some frog inside a very, very strong electromagnet
Count yourself lucky (see above). I think the frog seemed to survive fine. Unfortunately they couldn’t ask it what it felt like. I imagine it might be a bit of a bugger if you’ve got metal tooth fillings (magnets induce electricity).
