HI again,

I read on the internet that depnding on the gaude size lets 18, it will take
more amp to generate the same EM strenght as with a 30 gauge. considering
there are the same weight of magnet wire to do the coil.
I am not finding much information on this ( different gauge size Vs coil )
on the internet.

The strength of the magnetic field will be determined by the number
of turns and the current in them, (Ampere-Turns) so the larger the
diameter of the wire, the fewer turns you'll be able to wind on a
given core and the more current you'll have to force through them in
order to equal the ampere-turns of a coil wound on the same core
with smaller diameter wire.
