Can anyone please tell me what is the criteria for choosing the appropriate magnetics for RJ45 connectors and How it is made up ?

Without further specifications, can we guess that "magnetics for RJ45 connectors" refers to an etnernet interface?
If so, there are different requirements for 100 and 1000 MBit/s PHYs, and partial differences between PHY types. So you better ask for the right magnetics for a specific PHY chip. It's usually specified in vendor datasheets and reference designs.
RJ45 with integrated magnetics versus separated transformer.
