Magnets and Levitation



Gauss Rifle
Code: GAUSSRIFLE
Price: $31.54
Quantity in Basket: none
The hard to find parts of the Gauss Rifle project.

Four 12mm gold plated supermagnets Nine nickel plated 5/8ths inch steel balls

You supply the ruler and tape.

CAUTION: Neodymium magnets are so powerful that they will break if allowed to jump together. Work with them on a steel surface to prevent jumping.

 



Rattlesnake Eggs
Code: EGGS
Price: $6.92
Quantity in Basket: none
Two polished hematite magnets in the shape of dirigibles. When they come together, they make a loud buzzing sound like a rattlesnake. Hold them an inch apart and toss them into the air for a startling experience. Great fun just to fiddle with in your hands. Powerful, pretty, and lots of fun.
 



Tiny Bead Magnet
Code: BEADMAGNET
Price: $0.82
Quantity in Basket: none
These tiny magnets are made of the same alloy of Neodymium, Iron, and Boron as our 12mm cube magnets.

These are small beads that string nicely on copper wire for the Curie Effect Heat Engine. They are also used in our Ring Launcher and Zip Rod projects.

They are plated in gold to seal the sensitive alloy from moisture. They are 3 millimeters in diameter, 2 millimeters high, and have a 1 millimeter hole in the center.

This makes a good sample for Gold, Neodymium, or Boron in your collection of samples for the Periodic Table of the Elements.

 



One 12 mm magnet
Code: ONE12MM
Price: $7.34
Quantity in Basket: none
These VERY powerful magnets are made of an alloy of the rare earth element Neodymium along with Iron and Boron. This is the most powerful permanent magnet alloy known.

These magnets are plated in gold to seal the sensitive alloy from moisture. They are cubes 12 millimeters on a side.

These magnets work great as the top magnet in the Magnet in Mid-air project because of their strength. We supply them in 4 packs because they are also ideal for levitating pyrolytic graphite.

CAUTION: Neodymium magnets are so powerful that they will break if allowed to jump together. Work with them on a steel surface to prevent jumping.
