Find the magnetic field at the center of a rectangular loop with sides 2a and 2b.(adsbygoogle = window.adsbygoogle || []).push({});

well ok due to the sides with length 2a

[tex] B_{A} = \frac{\mu_{0} i}{2 \pi B} \frac{A}{\sqrt{\frac{A^2}{4} + B^2}} [/tex]

and due to 2B sides

[tex] B_{B} = \frac{\mu_{0} i}{2 \pi B} \frac{B}{\sqrt{\frac{B^2}{4} + A^2}} [/tex]

adding these two up yields the answer? Is this right? Please advise! Thanks!
