Answer:
Magnetic field at the center will be
![215.314* 10^(-7)T](https://img.qammunity.org/2020/formulas/physics/college/tmv9gel2mb3isy87k5quggjcr57m82vnqr.png)
Step-by-step explanation:
We have given that diameter of the loop d = 14 cm = 0.14 m
So radius
![R=(d)/(2)=(0.14)/(2)=0.07m](https://img.qammunity.org/2020/formulas/physics/college/6sywo5qnzrqyfghuhz2ttw5s2ydodwdk8v.png)
Current in the loop i = 2.40
We know that magnetic field at center of circular loop is given by
![B=(\mu _0i)/(2R)](https://img.qammunity.org/2020/formulas/physics/college/b69af84xog0zhvvw6ekbbdnm2l9ulhpsro.png)
So
![B=(4\pi * 10^(-7)* 2.4)/(2* 0.07)=215.314* 10^(-7)T](https://img.qammunity.org/2020/formulas/physics/college/euvguixiq8jpb8jm13lav8wk0t7lay7ezw.png)
