The dipole moment of a circular loop carrying a current \( I \), is \( m \) and the magnetic field at the centre of the loop is \( B_{1} \), When the dipole moment is double by keeping the current constant, the magnetic field at the centre of loop is \( B_{2} \), The ratio \( \frac{B_{1}}{B_{2}} \)
