Question: A long wire with a square cross - section 1 0 cm on a side carries a current of 2 8 A that is uniformly

A long wire with a square cross-section 10 cm on a side carries a current of 28 A that is uniformly distributed over the cross-section of the wire. What is the value of the integral \(\oint \) B \(\cdot d \mathbf{d s}\) along a square with side length 10 cm concentric with the wire and with sides parallel to those of the wire?
