You are buying ONE lot of 4 Magnets.
Size: 1 inch long x 1/2 inch wide x 1/8 inch thick Block
Nickel (Ni) Plated (silver-like shine)
Grade: N48 - Extremely powerful magnetic material
Pull Force is approximately 9.8 pounds per piece against a 1" steel plate
NEODYMIUM MAGNETS ARE NOT SAFE FOR CHILDREN
These blocks are magnetized through their thickness, so the strong North/South poles are in the center of the large planes.
That makes them easier to stack face to face than narrow edge to edge.
*** CAUTION ****
These are very strong mangets! They can be very hard to pull apart. These magnets can fly together very quickly - watch your fingers.
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?
Honestly, I like to simply play with them, 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.
