Here’s another interesting scientific experiment with neodymium magnets. This fall effect slowed many of you have already seen, it is caused by eddy currents generated by the magnets in a non-ferromagnetic metal that passes by. The curious part of this experiment is how they behave the coins in some parts of the shifting path horizontally.
The magnets are arranged as follows
A coin made of highly conductive metals, such as aluminum or copper, easily runs from left to right magnets matrix, but going from the top down is suppressed due to the eddy current.
Here are the magnets that I have used for this experiment
