Magnetic Field HELP: Factors Affecting Coil Strength

[duoheer]

Hey ppl. For the magnetic fileld of a current-carrying coil, what are the factors that affect the strength of the magnetic field due to the coil? THANKS

Um ...

(a) "current carrying" should be a serious clue.

(b) what physical properties of a "coil" could possibly influence the strength of the magnetic field?
