Radius of the loop = $5.065\times 10^{-3} m$

Explanation:

The magnetic field at the center of a circle is given by the formula

$B= \frac{\mu I}{2B}\\\\$

where I current = 4.2A

Magnetic Field , B = $5.21\times 10^{-4}$ T

$\mu$ = $4\pi\times 10^{-7}\times 4.2 H/m$ ( permeability)

plugging in the parameters and evaluating, we have

$\frac{4\times\pi\times10^{-7}\times 4.2 }{2\times5.21\times10^{-4} }$

= $=5.065\times 10^{-3}$

The radius of the loop = $5.065\times 10^{-3} m$
