Magnetic Shielding

I made this rather simple video this morning showing a physics demonstration on the effect of magnetic shielding. A paper clip is shown to be attracted to a magnet. A series of objects are placed in between, such as a plastic ruler, a steel ruler, a steel bookend, and some coins of different alloys. It

Elevator Physics

In a recent IP3 class on Newton's 2nd Law, the students were presented the "Elevator Problem" based on the THINK Cycle approach - a version of inquiry-based learning that was started in Temasek Junior College, Singapore. The "Elevator Problem" is a physics phenomenon observed in an everyday experience that students can relate to quite easily. It is presented to

Newton's Nightmare

This demonstration is called Newton's nightmare because it involves the slow dropping of a magnet that seems to be inconsitent with gravitational acceleration. Using the "CFILE" structure, we can explain how the magnet moves much slower in a metal pipe than when it is undergoing free fall (as in the PVC pipe, which serves as

Continue reading Newton's Nightmare


I didn't want to spend money on buying a piece of pyrolytic graphite and large neodymium magnets so I made do with what I have to make the following video. While diamagnetism is not in the A-level physics syllabus, it's good for students to know that there are other classifications of magnetic materials. What we
