    Need Direction in Life? USE A COMPASS!
    {http://www.knowledgerush.com/wiki_image/2/25/Compass_thumbnail.jpg}
    By Ann Cleven
    Have you ever gotten lost and lost all sense of direction? Imagine losing your sense of direction in the middle of the ocean! Compasses are vital to navigation while sailing so sailors can have an understanding of their location and have the ability to navigate where they are heading.

    This is an explanation on how to make a LARGE SCALE Electro-magnetic pulse bomb. But first, an explanation of what an EMP actually is.
    For those who do not know, an EMP (Also known as "pinch") bomb is a, well...bomb, but instead of exploding in fire and death, it unleashes a pulse that instantly deactivates any electronics within its range. It is completely harmless to humans (unless they are on an electronic life support system, I.E: Pacemaker).

    ...
    When you go to play a song the recording with cause the wire in the electromagnet to have a negative charge one way and a positive charge the other like a single circuit. During the process of listening to a song the charge will reverse side multiple times. Each time the charge is switched it causes the electromagnet to either attract or repel from the constant magnetic field applied by the permanent magnet. From previous chapters we learned about (+, -) charges and how they react to each other. This is exactly applied to this situation of like charges repelling and opposite charges attracting. As this process continues it causes the electromagnet to rise and compress the diaphragm attached to it. When this process is in action the sound it emitted causing different beats to come out as the electromagnet is attracted and repelled.

    (The picture above is from the site, but without animations. It is a cut open version of a speaker and gives great detail to what each part of the speaker is.)
    This video describes how a speaker works, by cutting open the speaker and allowing the insides to be exposed. With highlighting and labeling it is a very well composed video.
