Question: How can a magnetic field produce a current?
Part P-1: The Galvanometer
Previously, you have used the built in functions of digital
multimeters to serve as a voltmeter or ammeter. In those
cases you learned how to avoid damaging the equipment
before you started the lab. Therefore, before starting this
lab let's investigate how a galvanometer works. A
galvanometer is shown in the picture to the right.
The galvanometer is designed to measure miniscule
values of current and because of that many galvanometers
do not have units on their face.

Explain your answer with your knowledge of physics and justify your answer based on what
you will be asked to do in this lab.
2. What kind of measurement issues could you have when using a galvanometer? Consider
how fast small levels of current might change. Make sure you explain your answer.
3. How could you damage your galvanometer and how could you avoid this? Explain your
answer.
