Could someone please help me with all parts of this question? Question 4 (20 marks) A long wire carries a current I. The current is perpendicular to a wire loop ABCDA that consists of two straight sections AB and CD, each of length 1, and two semi-circular straight sections: BC, with radius a, and DA, with radius b. The semi-circular sections have the same centre of curvature that coincides with the wire. The current produces a magnetic field of magnitude'...
