PHYS 205 Lab Manual

Experiment 5  Electric Motor


Procedure

In this experiment you are to construct a simple electric motor and demonstrate how it works. For this purpose, you may need the following items, which should be included in the lab kit:

The additional items required for the setup will depend on your design. It is not recommended, however, that you purchase any expensive equipment or material for your project.

Safety Note

Before you begin, review the whole procedure to make sure you understand all the steps involved. Perform proper risk assessment and do not carry out the experiment if you feel that the procedure, equipment, or material pose any safety issues. Remember that safety comes first, and you must always ensure the safety of yourself and any person at your location. Do not attempt a design setup that might cause any type of harm or injury to yourself or others. Do not use any power source that exceeds 9 V. If you have any question or concern, please contact your tutor.

You are not restricted by a specific procedure in this lab. Your goal is to construct a simple electric motor from scratch, and demonstrate that it functions as intended. You have some freedom in building the design of your choice. However, make sure that your electric motor

  1. is safe to handle and operate.
  2. is assembled by you, using basic components.
  3. works, by continuously rotating for a minimum period of 30 s.
  4. does not require more than a 9 V battery (3 V battery combination preferred).

You are encouraged to solicit design ideas from external sources. In particular, a lot of interesting designs are displayed on video-sharing sites. Feel free to imitate any setup that you like, provided that you satisfy the four requirements stated above and clearly reference all your sources. Take multiple pictures (and/or videos) at different stages of the construction process. The pictures should be clear and sufficient in number to describe your procedure.
