43 grade OPC Cement it denotes the compressive strength of concrete in 43 Mega pascals will attain in 28 days. it is normally used for pavements, Non RCC structures and which are not important for initial strength. where as 53 Grade OPC Cement it denotes the compressive strength of 53 Mega Pascals will attain in concrete with the 28days, and it is used for RCC strengths and which are important to gain initial strength.
no,beacuse inside the earth the core is present due to flow of electrons it attain magnetic properties
Concrete attains 60% of its strength in 18 days it may take a full year for all chemical reactions to cease and attain its full strength

Magnetic induction B = mu * n * I Here mu is the magnetic permeability of the core material. n - the number of turns per unit length and I - the current in ampere. So as number of turns increases the magnetic effect too increases
