Steel Balls Metal Ball Bearing – (Not Magnet!)
Diameter 8mm, 10mm, 12mm, 15mm, 18mm, 20mm and 25mm
These metal steel balls are Not Magnet, but they can be attached to magnet.
Meaning these are ferrous metal that is receptive to magnets but metal steel ball by itself has got no magnetic field.
This is NOT a TOY!
Not Suitable for Children below age of 14.
Small Parts, Swallow Risk.
Do not leave unattended on floor, might cause fall injury.

For Home, Science Lab and Classroom
Build a Simple but Fun Magnetic Gauss Gun a.k.a. Magnetic Rail Gun
Place 2pcs of cylinder neodymium magnets with 2pcs of steel balls (10mm and 12mm dia. steel balls were used in this video) for each section, create 3 such section and place them inside the PVC conduit about 7-10cm apart with the steel balls all facing towards the target.
Gently roll a steel ball towards the neodymium magnet of the 1st section and watch the chain reaction from the force created by the pull of neodymium magnet on the steel ball.
The energy get transferred from one section to the next with the final ball “shooting” out from the PVC conduit.
Experiment with more sections, magnets and different sizes of steel balls!
Steel Iron Ball Bearings Various Metric Sizes
These common steel balls are not magnets!
However they are ferrous metal that attracts magnets.
Use these for pairing with magnets, science projects or experiments.
