<p>Hey guys, I took apart a portable room fan and notice the motor part has copper wiring around a magnet, can someone explain the function of this? It'll be nice if you can explain how the fan works. Thanks</p>

<p>Here are some pictures:

<p>I hope you can put this thing back together again, with no extra pieces lying around. </p>

<p>You could’ve looked into Wiki, How Things Work, or goog your answer. </p>

<p>Do you know about how magnets repeal like poles and attract opposing poles? The electric energy is creating like and opposite magnets which causes the rotor to turn and thus mechanical energy is made. That’s about it.</p>

<p>That’s a shaded-pole motor: [Shaded-pole</a> motor - Wikipedia, the free encyclopedia](<a href=“http://en.wikipedia.org/wiki/Shaded-pole_motor]Shaded-pole”>Shaded-pole motor - Wikipedia)</p>

<p>I think you need to understand something simpler such as a DC motor:</p>

<p>[HowStuffWorks</a> “How Electric Motors Work”](<a href=“http://electronics.howstuffworks.com/motor4.htm]HowStuffWorks”>How Electric Motors Work | HowStuffWorks)</p>

<p>You wont understand the specifics until you take physics or an EE course.</p>
