Small steel balls with diameter of 1/8 inch (about 3 milimeters) are used in mechanics and magnetism experiments. As a substitute for iron filings for studying the phenomenon of magnetic fields. Form clusters and chains between unlike poles of magnets. Made of polished, hardened spheres.
For studying magnetic phenomena such as operation of a compass, testing of magnetic poles, finding the direction of electric current etc. Consists of a magnetised steel needle with brass bearing. May be pivoted on a non-magnetic metal stand. North pole is marked in red. Available in 2 sizes. Use it to make a compass for class project. Can be remagnetized using any strong magnet.
This tube contains many different, loose steel shapes. They are ideal
for experimentation with magnetic fields and are a bit larger than the very fine
iron filings. With these steel shapes you can also measure magnet strength
by counting how many of these shapes are attracted to the magnet.
Iron filing, 12 ounce, in a shaker for convenience plus screw cap for safe-keeping. They are ideal for
experimentation with magnetic fields. When you place these filings on any
magnet, you can visualize 3D magnetic fields. This demonstration is very
common in the classroom and this is your chance to further study the magnetic properties at home.
