no,chalk is not magnetic because it is not made out of either iron or steel or otherwise it is not made out of meatal
Simple: chalk dust has no magnetic properties whatsoever, and is an insulator. As such, the magnetic field will flow right past it as if it weren't there, so it cannot position itself accordingly.
Chalk dust (calcium carbonate) is not magnetisable.
Because they have different magnetic properties; iron is strongly ferromagnetic.
A separation technique is something used to separate an object from it's mixture. For example, in a bowl you have chalk, chalk dust, salt, and paperclips. You'd use magnetic attraction to get the paperclips out. Then you'd use your hands and take out the chalk. And then, you use a sifting tool and it'll separate the salt and chalk dust by itself. But, another cool way to separate those two is to put them in water. The salt will eventually sink because it's denser than water, and the chalk dust will float because it is less dense. Other techniques are, filteration, sifitng, magnetic attraction, evaporation, chromotography. Hope that helped! :D

No well i am just telling you the answer i think because i went to a school that had chalk boards.

chalk is an insulator because heat does not flow through it as easily.

rubber is harder than chalk !
Use a magnet to remove the iron filings. Filter the remainder to separate the insoluble chalk powder from the water. Wash and dry the iron filings as they will be contaminated. Dry the chalk powder to remove traces of water.
There are a couple of things that make chalk hard. The calcium in chalk is said to make chalk hard.
