Description
We employ this precise formula to validate our design, which is currently in the conceptual stage. As outlined in the lab instructions, our objective is to create an AC generator. To achieve this, we were supplied with two magnets and a coil. Our approach involves rotating the magnets around the coil to generate a magnetic field, as depicted in the accompanying image. The ultimate aim is to observe the voltage waveform it produces on the oscilloscope. This encapsulates the core conceptI will also need on the side an executive summary

Exploring Electrical Power Generation
Goals:
In this laboratory project, you are tasked with understanding and demonstrating a simple electrical generator.
Your task will be to provide a succinct history of electrical generators and their evolution (including the
invention of the Faraday disk homopolar generator, AC generators and commutated DC generators), a
physical description of all parts and their purpose, a simple AC generator design of your choice, a
mathematical description of how your generator design operates, and test results showing the voltage and
current waveforms produced by your design.
There are several different methods which you can use to realize the generator. Any of these are acceptable
as long as your design produces an AC current and you can provide a mathematical analysis of your design.
Assignment:
You will design and build an AC generator based on a simple coil/permanent magnet combination and
provide a complete description of it in your report. The description will contain a mathematical model that
represents the operation of the generator, a diagram and pictures of it, and a vector schematic that describes
your mathematical model. Experimental results will include current and voltage waveforms output by your
design.
Your report should include
Discussion of current electrical generator designs and their relation to your design (i.e. what was changed
and why), clear physical description of the generator design and its key parts (use images)
Mathematical description of the current/voltage (theoretically) produced by your generator, i.e. a
mathematical model of your system which provides the expected output (not only the peak values but
also the waveforms)
Picture(s) of your final generator device and test circuit with circuit diagram
Test results of the voltage and current waveforms produced by your generator design
Comparison of model and experimental results: comparison of measured and calculated
voltage/current waveforms, discussion of whether the induced current on the current loop meets your
expectations and why. Reference your waveforms and discuss referencing your mathematical model.
Bonus: (10 pts)
1. Modify your generator design to produce DC output (diodes and external circuits are not acceptable,
do not use a Faraday Disk).
2. Describe the adjustments you made and how they result in DC current production.
3. Generate voltage/current waveforms to show DC production

Deliverables:
A comprehensive report that has a continuous flow without any breaks or abrupt transitions. Everything
in the report should serve a purpose and the report should reflect what you learned in this lab project. Focus
on critical analysis, justifying your answers/conclusions with data from simulation/calculation/experiment as
well as references (where appropriate). Be sure to provide enough practical information to ensure the reader
can understand what you did and how to interpret the results.
A single Lab Report must be submitted for the team. Each team member is required to submit separately a
one-page Individual Executive Summary. Your Lab Report should contain:
1. An Abstract summarizing the lab and your results/conclusions.
2. An Introduction section that “sets the stage” for your report. You may think of a structure like a funnel,
starting with knowledge understood by a sophomore EE student and gradually becoming more focused until
you get to your specified task.
a. A short discussion/introduction to the problem and the history of electrical generators; provide a short
summarized timeline of important developments
3. A section (can be called Background, theory, or the like, but choose what fits best for you) detailing the
necessary background information to perform the task at hand. Introduce the concepts that you need and
derive the formulas that you will require.
a. E.g. relevant derivation of the emf produced in the generator designs with details about the assumptions
made and the overall mathematical model of the system. How you develop the mathematical model, how
you map out the variation in magnetic field/flux, etc.
4. A section detailing the Methods and Results produced in the lab as described in the Assignment section.
Explain the experiment that you have designed to test or solve the problem at hand and the logic behind your
approach. Present your results and your analysis/discussion. If there are multiple outcomes, you may elect
to create separate “methods/results” sections for each outcome. Think logically about the order to improve
the flow.
a. Justify your design choice, explore the effects of changes in parameters of your design, compare your
estimated numerical outcomes from your mathematical model with your measurements, discuss reasons
for any discrepancies.
b. In this section you should include sufficient graphs, plots, data to argue your points (see assignment).
Think critically about your results and process when discussing. What worked and did not work? Why?
c. Figures (schematics, simulation screenshots, plots, etc.), tables, and equations must be clearly legible,
neat, and appropriately numbered in the order they appear (e.g. Fig. 1, Fig. 2; Table 1, Table 2; Eq. 1,
Eq. 2, etc.) and must be properly cited in the text of the report (e.g. as shown in Fig. 2 …, Table 1 tabulates
…, According to Eqn. 3 …). All figures and tables should contain sufficiently detailed captions.
5. A Conclusion section which provides a “so what” of the report. Why should someone care about this result?
You may briefly summarize your process and results, but do not just summarize. Aim to add new thoughts
in this section. Did you meet the specifications or constraints? If not, what can you do better?
6. References must be provided at the end of the document. A minimum of 10 references is required for every
report. Your references should consist of published journal papers, textbooks, databases, etc. Items like
Wikipedia, online lecture notes, news articles, etc. will NOT count towards your 10 references. If you find
something useful in these items, cite the original source, e.g. references at the bottom of a Wikipedia page.
7. A list of your team members, their individual contributions. Provide detailed contributions. If a specific
member is significantly less involved than others are, they will receive reduced credit. Be sure to involve
other members and work together on the project/report.
8. A signature from each member attesting that all members contributed equally to the project.
Page Limit: 8 pages not including references, contribution, and signature pages (9 with Bonus).
Failure to satisfy these requirements will result in a reduced grade.
