  • 071 - Electromagnetic Induction
    In this video Paul Andersen explains how electromagnetic induction occurs when the magnetic flux of an object changes. The magnetic flux is product of the surface area perpendicular to the magnetic field and the magnetic field strength. Microphones and generators are examples of devices that utilize electromagnetic induction.

    This video set off a lot of light bulbs in my head. Thanks for sharing this. I didn't understand why there was only current when the objects were in motion until the magnetic field pointers were shown in the background. The polarity of the object moved through the coils causes the electrons in the coils to move around and re-order themselves, which creates current in the coils. Thus, at any point if you stopped moving the object, the electrons in the coils would have no reason to move, therefor creating zero current. Am I understanding this correctly? This electricity shit is blowing my mind. And the fact that there is this "conventional" and "reality" way of describing what is happening in the circuits doesn't help me one bit to understand. Some professors will say "as the positive charges moves", others will say "as the electrons flow"....jesus christ make up your damn mind so I can understand! ... ok sorry ranting now lol, back to learning physics. Great video!
