2. What happend to the soil dusts as the magnet is near into it?

—This usually follows the static electricity one, because it talks not just about magnetism, but also about electromagnetism. In fact, getting across the idea that the two concepts are intimately connnected is the main goal of this demo.

3.What do you call those materials like stample wires and nails that were attracted to Magnet?

—Those materials which are attracted b a magnet are magnetic materials. Iron, Nickel, and Cobalt are the magnetic substances as objects made up of these materials are attracted by a magnet.

4. Can you give other substances or materials that can be considered as magnetic?

—Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include the elements iron, nickel and cobalt and their alloys, some alloys of rare-earth metals, and some naturally occurring minerals such as lodestone.
