My Students

The AP Electricity and Magnetism class is a group of intensely gifted and intelligent students. These students are taking their second college level physics class in high school, and almost all of them are hoping to pursue either physics or engineering in the future.

These students thrive with new ideas and love to learn.

They are extremely capable and love to be challenged with complex problems and abstract concepts. Supporting these students means introducing them to properties of the universe they didn't even know existed, and giving them the tools to test it.

My Project

The Jumping Ring demonstration is a classic physics demo to illustrate how Lenz's Law and Faraday's Law work together to produce electric currents. The demonstration surprises students and encourages them question their understanding of electricity and magnetism.

From only seeing the demonstration, students will need to try and explain the seemingly magical phenomenon of a metal ring jumping several feet into the air.

This is a great project for these advanced students because it challenges them to combine their knowledge gained through two years of physics; building their own equations to solve a complex problem with a hands-on real demonstration.
