How the formula arises ?

We can use the Biot-Savart law to find the magnetic field due to a current. We first consider arbitrary segments on opposite sides of the loop to qualitatively show by the vector results that the net magnetic field direction is along the central axis from the loop. From there, we can use the Biot-Savart law to derive the expression for magnetic field. The magnetic field lines will be less denser in the region near the circumference of the loop than at the center. Thus, the magnetic field will be stronger at the center of the loop than in the region near the circumference.

FAQ

What is field at the center of the ring?

field at the center of the ring is given by B=μ0I/2R(at center of loop), where R is the radius of the loop. RHR-2 gives the direction of the field about the loop and is represented as M=([Permeability-vacuum]*i)/(2*r) or field at the center of the ring=([Permeability-vacuum]*Electric Current)/(2*Radius of ring). Electric Current is the time rate of flow of charge through a cross sectional area and Radius of ring is a line segment extending from the center of a circle or sphere to the circumference or bounding surface.
