Possible source of error in this lab?

Click For Summary
SUMMARY

The forum discussion centers around a lab assignment where the user is seeking clarification on potential sources of error in their experiment. Key points include the impact of electrical resistance, temperature, and the non-uniformity of the magnetic field on measurement accuracy. The user expresses confusion regarding the previous lab's grading, specifically about the dependence of gravity on location. The discussion highlights the importance of understanding measurement limitations, particularly with the ammeter used in the experiment.

PREREQUISITES
  • Understanding of electrical resistance and its effects on measurements

The Attempt at a Solution


I have no idea,
the previous lab i put gravity depend on location, but the teacher marked me wrong
If anyone can give me some hints, and i need 3...
I don't know if this 2 are right
electrical resistance
temperature
ty!

Well, Laura can't exactly make the magnetic field disappear for the wire outside the 0.025 m section she's considering. The ammeter is also going to be inexact. There might also be some problems with the magnet's field being non-uniform, but unfortunately we don't know what exactly she's trying to measure here.
 
ty for replying!
i have the data,
