Question
A mixture of A and B is taken in China dish. If the magnet is brought near it, substance B gets attracted to this magnet. This substance B clings to the poles of magnet and gets separated. The remaining substance A when heated, it directly converts into its vapours.
Identify these substances A and B of given mixture from the following:
- A = Camphor, B = Aluminium powder
- A = Camphor, B = Nickel
- A = Nickel, B = Camphor
- A = Cobalt, B = Coal
Hint:
A- Nickel, B- Camphor.
The correct answer is: A = Nickel, B = Camphor
The substances which are attracted towards a magnet are called ferro-magnetic materials Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include iron, nickel, cobalt, some alloys of rare-earth metals, and some naturally occurring minerals such as lodestone.
