Electromagnetic

The modern era is based not just on electricity, but the relationship between electricity and magnetism, and the fact that electricity can create a magnetic field which causes repulsion/attraction to other magnetic fields. This creates mechanical motion.
The electric motor.
Run backwards, mechanical motion can generate electricity. By a process called induction, a magnet moving relative to a coil of wires will induce a current in the wire.

We talked for about 45 minutes on Block day about these connections/relationships, and now on Friday we will be in the computer lab doing some further investigations of the phenomena.
This includes using Crocodile Physics (see link from a week or two ago to download it) as well as simulations and visualizations online.

The following links are from the worksheet that we are working on in the computer lab.
