Magnets are a classic example of technology that people THINK they understand.

This disconnect between THINKING you understand, and ACTUALLY understanding, has allowed much misinformation to spread about what magnets can and cannot do.

Perhaps the most common, and most ridiculous, claim is the generation of "Free Energy" using magnets.

Using the concepts you have learned so far in this Module, analyze the device shown in the video below:

https://www.youtube.com/watch?v=jiAhiu6UqXQ

This is NOT a free-energy device, but the misleading video suggests otherwise.

What is wrong with this device? Why won't it run forever?

In your answer explicitly mention the contributions of the following:

  1. Electromagnetic Induction
  2. Lenz's Law
  3. Friction
  4. Magnetic Field Lines
