How does the number of coils of wire in an electromagnet affect its magnetic strength?

I have to do a write up about this. I performed the experiment but I don‘t really get why I had to keep my current the same (at 0.50)And i‘ve been asked to do an abstract too! and i dont know what an abstract is on essays?And I also feel like my introduction, conclusion and result are the same cause they all basically say the more coils wrapped around the electromagnet, the stronger the magnetic strength iswhich is annoying cause I feel like i‘ve been repeating myself numerous of times.help please

Answer:

metal. they dont brake as easy and r way cheaper

plain metel with no colors are called speed braces, theyre smaller and easier to clean than normal ones. i have th colored ones, trust me they suck! GET THE SMALL ONES!!!!!!!!!!!!!!

In general, for a given current increasing the number of turns will increase the strength of the field, up to the point where the core saturates.
