I have a rectangular wire loop that lies in the xy-plane. The left edge of the loop is on the y-axis.The x-dimension of the loop is 110 cm and the y-dimension is 40 cm. If the loop is immersed in a non-uniform magnetic field B=[2x^5+3x^2-4x+3] i hat+[2x^5+3x^2-4x+3] k hat. What is the magnetic flux through the loop? Is the magnetic flux found the same way as if the field was uniform, i.e. integral of B dot dA n hat?
