Answer:
Explanation:
Magnetic properties of a material depend upon the atomic structure. Every element atom has electron that spin in pair. They form dipole. These dipole are responsible fort the magnetic behavior of the substance. There are many classification of a magnetic material. Here we are distinguishing between two such substances.
For column A ( Paramagnetic ) :
- A substance that has unpaired electron
- A substance that is attracted to external magnetic field
For column B ( Diamagnetic ) :
- A substance that has paired electrons.
- A substance that is weekly repelled by an external magnetic field.
- A substance that has zero magnetic moment
