Toys which I mentionet don't use anti gravity at all but they could be commonly and nonscientificaly referred as "anti gravitional" only because they can float over the ground.
Note that as it's said in Faraday's Law EMF is equal to d(N*magnetic_flux)/dt where N is a total amount of wire turns and magnetic_flux is per each one.
In your example your, magnetic_flux is const. and equal to BS=pi (r)^2 B. And only N changes in time. Try to think about dependence between...
