Electromagnet Lab Procedure Questions

I was wondering how to connect a battery to a solenoid that we are making from wire in our Electromagnet Lab. Priyansh and I are determining the affect on the strength of the electromagnet by changing the length of the wire and therefore, the number of coils in the solenoid. We wanted to use a battery to cause induced current and with a compass find the direction of the field. We wanted to attach an ammeter and the battery to it to find the current and cause the current and were wondering how we would attach it. Hope to hear back soon, or a reply on the googledoc!

Ohm's Law Lab

Do we need to do an error analysis in the conclusion? I wasn't sure, since it wasn't on the template, but we've always done one.
