Title:
Describe the specific content of the lab in a concise fashion.
Abstract:
Summarize the main ideas of the introduction, your methods,
your results, your discussion, and your conclusions in a
sentence or two for each section. The abstract should be written
in the past tense. It should include no equations, and the

abstract should consist of a single paragraph. What the abstract
should not be is a miniature introduction.
Introduction:
The introduction is to be at least one page in length. The
introduction should state the concept to be examined, the
specific question(s) asked and the expected outcome. It should
also showcase your understanding of the physical principles
involved in the experiment, any formulas used in the analysis,
and any relevant background concepts.
A high quality introduction will state the experimental concept
clearly, and logically relate this concept to supporting
background information. It will state the hypothesis clearly and
precisely, and relate the hypothesis to both the experimental
setup and the module learning outcomes.
Methods:
Provide a concise, easy-to-follow description of the specific
procedures followed in the experiment. Give enough detail of
both the materials and the procedure used so that the experiment
could be replicated by someone who has never done it before.
Do not copy and paste, or simply repeat the directions given in
the course materials.
A high quality methods section will be complete and accurate.
The information will be well organized, and give clear, accurate
and complete steps to follow.
Results:
State the overall findings of the lab. This section should begin
with a paragraph containing any hypotheses formed and tested
during the conduct of the laboratory. This section should also
contain any data collected, sample calculations, analysis, and
plots of the data or results. Describe these results with visuals,
such as tables or graphs, in the order that they matter within the
experiment or tell the story of the data. Describe trends and
supporting information details that promote understanding of
the visuals without making conclusions about the data, as this
will come later in the conclusions section. Refer to visuals as
Table 1, Figure 2, etc.

A high quality results section will provide the raw data in a
complete and well organized manner. Any mathematical
analyses and explanations will be clear and show a complete
understanding of the results reported.
Discussion:
Explain what the findings of the lab mean in terms of the
scientific concept or procedure that the lab is about. Be sure to
point to the specific data from your findings as support for your
explanation. Discuss any answers to the questions you raised in
your Introduction, and address other issues that may be
appropriate.
A high quality discussion will offer a thorough explanation and
analysis of the experiment, interweaving the hypothesis with
substantial readings and overarching themes.
Conclusion:
State what you have learned about the main focus of the
experiment, the scientific concept, or the lab procedure. Give
enough details of what you have learned to be convincing, and
describe anything else you may have learned from doing the lab
and writing the report: for example, something you found
particularly interesting, methods of analyzing data you found
useful, anything about using a spreadsheet or graphing, etc.
A high quality conclusion will offer insights connecting the
experimental setup with the hypothesis and the physical
principle under investigation.
Writing and References:
Include all the sources you have used in writing your
experiment report, such as a lab manual, a textbook, and any
reference books or articles you cited.
· Use the appropriate documentation style for citations and
references (CBE, ACS, etc.)
· Use the correct format (titles, captions, etc.) for the tables,
graphs, and drawings
· Write in a scientific style (tone should be objective; sentences

should be clear and to the point)
· Make sure your report is clear of spelling and grammatical
errors (use the spell check on your computer
· Include all the necessary headings if you do not use the
template accessible next to this document within the Experiment
drop box.

While completing the experiment Electromagnetic Induction,
make sure to keep the following guiding questions in mind:
· Is the magnitude of the magnetic field the primary determinant
in the Emf induced in the coil? If not, then what is the primary
determinate of the magnitude of the induced Emf?
· How is relative motion between the field and coil induced?
What controls do you have for changing the relative motion?
What is the relationship between the units of RPM and radians
per second?
· How can ratios be used in an experiment when data is only
available in the form of relative magnitudes?
To complete the experiment you will need to:
1. Be prepared with a laboratory notebook to record your
observations.
2. Click the image to open the simulation experiment.

3. Perform the experiment as described.
4. Transfer your data and results from your laboratory notebook
into the lab report template provided at the end of this
experiment description.
5. Submit your version of the laboratory experiment report.
In your laboratory notebook, you will collect data, make
observations, and ponder the questions posed within the lab
instructions. Thus, the notebook should contain all the data
collected and analysis performed, which will be invaluable to
you as you write the results section of your laboratory report.
Furthermore, the notebook should contain your observations
and thoughts, which will allow you to address the questions
posed, both for the discussion section in the laboratory report
and in helping you to participate in the online discussion
included in the module.
M4A1 Experiment: Electromagnetic Induction
PART I - Faraday’s Law and Relative Motion
Start the simulation “Faraday’s Electromagnetic Lab ” by
clicking on the image below:
http://phet.colorado.edu/sims/faraday/faraday_en.jnlp
http://phet.colorado.edu/sims/faraday/faraday_en.jnlp
· Select the tab labeled “Pickup Coil.”

· Move the bar magnet to various static (“nonmoving”)
positions.
Note that any static position from which the magnet seems to
induce a potential in the coil seems to cause the bulb to shine
brightly. Try various static positions, including near and far
positions. Use the simulation controls to flip the field. Note
your observations in your laboratory notebook. Pick other
controls available in the simulation to vary the field. What do
your observations imply about the magnitude and direction of
the magnetic field in inducing an electromotive force in the
pickup coil? Do your observations indicate any other factors
that might induce an EMF in the pickup coil, and thus, cause the
bulb to shine?
Note any factors that will induce an EMF in your notebook.
Investigate the general relationship between the magnitude of
the bulb brightness and the particular factor you are
considering. Your investigation should indicate whether bigger,
faster, further, or more causes the bulb to burn brighter than the
converse.
Part II - Parameters effecting Generator Performance
· Select the generator tab of the simulation.
· In the simulation, controls select the voltmeter to replace the
bulb.
You will note that the voltmeter scale is not calibrated, but that
you can still compare various potential readings by counting
“tick marks” on the face of the meter. Using this scale to collect
data, vary the relationship between the maximum electromotive
force EMFmax produced and the various parameters in the
generator equation, EMF = ωNBAsin(ωt). Specifically, vary the
angular frequency (ω) (by adjusting the water flow through the
spigot on the left), number of loops (N), and area of the loop
(A). Choose one parameter and produce a plot of EMFmax vs.
the parameter. Be sure to use at least 10 data points. Record the
results in your laboratory notebook.
PART III - Calibrating the Galvanometer
The voltmeter scale is uncalibrated in part because we are

missing two values: 1) the average of the peak magnetic field
strengths across the surface bounded by the loops in the pickup
coil, and 2) the maximum area of the loops of the pickup coil.
Given that the maximum area of the loop is 0.75m², and the
maximum magnetic field strength at the location of the coil is
0.6 T, you should be able to find the value of a single tick mark
on the voltmeter scale.
In your laboratory notebook write down a detailed procedure for
doing so. Carry out this measurement with angular speeds of 25,
50, and 100 RPM. Are these values comparable? Do they need
to be for the meter to be useful? Why or why not?

· Write an introduction of at least 1 page in length. The
introduction should showcase your understanding of
electromagnetic induction.
· Write a methods section describing in your own words the
experimental procedure used to complete each activity. Do not
copy and paste, or simply repeat the directions given in the
course materials.
· Write a results section. This section should begin with a
paragraph containing any hypotheses formed and tested during
the conduct of the laboratory. This section should also contain
any data collected, sample calculations, analysis, and plots of
the data or results.
· Write your discussion section specifically addressing how
your results did or did not support any hypothesis used in this
laboratory.
· Write your conclusion. This section should be brief, at most,
one or two paragraphs; connect the discussion with the
information contained in the introduction.
· Write the abstract. While this is the first section of your lab
report, it should be written last. This section should be written
in the past tense, in the third person, and should be a summary

of the entire laboratory report.
