Plot A using quiver . (Note: let so that ) Answer: Problem 3. A line current I flows along a straight line from P(3,2,1) to Q(1,2,6). I is A. Find magnetic flux density B from Biot-Savart’s Law at point P(3,4,5). Also find magnetic vector potential A at this point. Note: the equation of the line from P to Q can be described by: where L is the total length of the line and l is the distance along the line from point P. Answer: Problem 4. Lonngren 3.3.8 Answer: Problem 5. Find magnetic flux density B for infinite surface current on xoy plane with density using Biot savart’s Law. Answer: Problem 6. Lonngren 3.2.5; Given a = 1, A/m 2 , plot B from 0 to 10a. Answer: Problem 7. Lonngren 3.4.1 Answer: Problem 8. Lonngren 3.7.1 Answer:...
