Answer in units oF mV. 004 (part 1 oF 2) 10 points Two circular planar coils that have 250 and 360 loops, respectively, and corresponding radii oF 0 . 2 m and 0 . 39 m share a common axis with the coil centers separated by 5 . 7 m and with the axis perpendicular to both planes oF the coil. The permeability oF Free space is 4 107 N / A 2 . What is the mutual inductance oF the coils? Hint: Use the Farfeld approximation. Answer in units oF H. 005 (part 2 oF 2) 10 points IF coil 2, carrying a constant current 32 A, is moving at a velocity oF 39 m / s along the axis, what is the magnitude oF the emf induced in coil 1 when the distance between them is 5 . 7 m? Answer in units oF V....
