Faraday's Law

Electric generators use the properties of electromagnetism to transform kinetic energy into electrical energy. Many electric generators work by spinning a permanent magnet near coils of wire. Experiment with this simulation of electricity generation to visualize how this process works. Once the simulation opens, try moving the permanent magnet around to see what happens. Also rapidly switch the polarity of the magnet by repeatedly clicking on the magnet icon at the bottom of the page, and observe the effect.

,Part A

Try moving the magnet in the different ways described in the table below,. Record your observations in the second column of the table.

• Move the magnet straight through the coil, leading with the north pole. Once the magnet is completely through, move it back to its original position.
• Movethe magnet straight through the coil, only this time leading with the south pole. Once the magnet is completely through, move it back to its original position.
• Put the magnet in the center of the coil, but don't move it.
• Put the magnet on the outside of the coil. Repeatedly move it up and down while outside of the coil.
• Keeping the magnet outside of the coil. Repeatedly move it back and forth horizontally.
• Place the magnet back inside of the coil. Now repeatedly switch the polarity of the magnet by pressing the button toward the bottom-right of the page over and over again.

Part B

After producing electricity in many different ways,describe what causes electricity to flow in the coil? In your response, describe the types of forces acting on the electrons and how they result in movement.
