Electromagnet Help! How to Make a Small but very Strong Electromagnet???

I need you help smart people of Instructables!I need to make a small Electromagnet, that uses minimum power (by that I mean the battery), but still has to be very powerful. I have a couple of questions that I need you to help me answer:Does the number of coils that is wound to the metal bar effect the strenght of the electromagnet?Does the wire gauge (20,24,28,30,34,36 wire gauge) make a difference is the strenght of the magnet?Does the voltage I supply to the coil effect the Electromagnet?What type of battery is best for an Electromagnet (AA, AAA, C, D), and what voltage (1,5V, 3V, 4,5V, 6V, 9V) ???Here is the thing, I need to make the Electromagnet super strong but taking up the minimum of energy, for example, just 1,5V. The things that are not important to me (doesn't play a factor in my device) is the number of wire winds to the metal rod and the wire gauge! So is it better to just make 1 or more (3,4,5,6...) layers of wire winds???Is it better to use thinner (36 gauge) or thicker wire (24 gauge)???Thank you a lot!Stanislav

Real-life Back to the Future 2 hoverboard

French artist Nils Guadagnin has built his very own hoverboard based on the hoverboards in Back to the Future II. It's pink, it's a board, and it actually does hover when placed on its platform. Integrated into the board and the plinth is an electromagnetic system which levitates the board. A laser system stabilises the object in the air. The board is hovering with the help of two CLM-1+ levitation modules made by Crealev. Hoverboard Project via geekologie

make your own black light ideas

So in order to make a black light i (the stupid half of me) would think to dip a lightbulb in black paint. i (the smart half of me) would assume there is more to it than that here is some random 2 facts about the blacklight (wood's light) it is not black its a deep-bluish-purple what a blacklight emits is: lamp emitting electromagnetic radiation my question is how could i make one and would it be cheaper to make it or buy it...
