Neodymium Magnets

Moving Things With NIBs

Moving Money

A legitimate U.S. bill has iron particles in the ink that are attracted to a magnet. In this experiment I use a powerful 2" by 2" by 1" thick Neodymium Magnet to attract the bill. This is a magnet with a pull force of around 325 pounds. Extreme care must be used when handling magnets this large.

Moving Grapes

This is an example of a diamagnetic effect. The grape consists mostly of water which slightly repels a magnetic field. I am using a pair of 2" dia by 1" thick Neodymium disks to repel the grapes. I wear a full face shield when I run this experiment to assure that my breathing doesn't effect the Experiment

Moving Water

Water is diamagnetic so I tried to manipulate an ice treat using a 2" cube Neo. By the time it settled down and the thread un-twisted it had melted.

I videoed this experiment after one YouTube viewer commented about the grapes being suspended on diametric metal (copper wire). Other than the magnet there is no metal involved with this demonstration.

Moving Heavy Metal

This is a video from my chapter on Eddy Currents. Here a sheet if 1/4" thick glass separates the magnet from the metal objects being moved.
