The magnetic field at the center of current carrying circular loop is $\displaystyle \mathrm{B}_1$. The magnetic field at a distance of $\displaystyle \sqrt{3}$ times radius of the given circular loop from the center on its axis is $\displaystyle \mathrm{B}_2$. The value of $\displaystyle \mathrm{B}_1 / \mathrm{B}_2$ will be
