As far as i know,levitation is not possible,as is levitating people.Levitation has not been yet proved and therefore assumed as fantasy,so i agree with zalkary.
As for magick,magick is spiritual and not physical,that being said,you cannot use it to accomplish impossible feats that are physical like levitating,flying,etc.Magick is working with the energies of the universe and it has its own limit,beyond which we cannot go.
As for spells and rituals,you need to learn and practise the basics first before jumping directly to casting.
The basics are meditation,visualisation,grounding,shielding,chakras,energy manipulation,auras.
And remember,you must have belief,will power and a strong mindset for your spells to work.
I hope you luck on you future endevours in magick.
