Electromagnetics

This week's Science Lessons:

Riddle. I have special properties that draw objects together. I amaze, delight, and help people every hour, day after day. I have a home in various places. When the stereo is on, I am there. When the doorbell buzzes, I am there. I even turn up in nature. (Look amongst the rocks.) You can't see or hear me. I am an invisible force. I keep things going with my attraction and repulsion power. I like to transfer my invisible power to other iron material. Can you guess who I am?

 Answer: I'm Magnetism.
Check out this cool trick done by electromagnetic Induction.
Here are some of the things we are learning from Khan Academy on Electromagnetics.
