One of the four fundamental forces of nature, the electromagnetic force is the one that binds atoms together, allows you to walk down the street, and is solely responsible for bad hair days worldwide. One of the greatest leaps in science was the discovery that the electricity and magnetism were a part of each other, and not separate.
By the time you’re through with this lesson, you’ll have created particle accelerators, galvanometers, curie heat engines, unipolar motors, listened to a magnet (no kidding!), and build a working DC motor. Are you ready? This video will get you started on the right foot for your study into electromagnetism:

It really depends on the size of the motor in the fan. The one I used worked on 3 volts from 2 AA batteries. You’ll want to hook up a digital multimeter to see how many amps get drawn so you can get the right solar cell to produce enough current to make the fan work.
Hi Aurora,
how many volts did it take to get the fan to move and how many volts did it take to get the light bulbs to work, in your video. I am trying to build a solar powered fan for my greenhouse and so your answer will help me with my project,
thanks
