North Pole is on the 2mm upper base, south pole on 3mm bottom base, making these magnets easier to stack than to join end to end.
These magnets find practical application in motors.
The metal coating is durable, but ALL Neodymium magnets can chip or shatter. If used gently, these magnets can serve you for a lifetime.
These Neodymium Iron Boron magnets are also known as "Rare Earth" or NdFeB magnets. Neodymium magnets are simply incredible!
They are far more powerful than those old horseshoe magnets most of us grew up with.
What can these magnets be used for?
They are fun to play with, but these magnets have many practical uses as well. Use them on the fridge. Put them to work in the tool shed.
Use them as fasteners on cabinetry. They are great for science experiments. You are limited only by your imagination.
