Impact of Coils on Electromagnet Strength by api-459203524 is a document available to read on EtoBox.

The document discusses an experiment conducted by students to determine how the number of coils affects the strength of an electromagnet powered by a 12-volt battery. Their hypothesis was that increasing the number of coils wrapped around an iron rod up to around 250 would make the electromagnet stronger, but after that the electrical charge would dissipate. Their preliminary tests with a smaller electromagnet setup worked. However, their full experiment found that with 225 coils the electromagnet could not
