Question

5 Curl and Circulation 5.1 Compute the circulation of the uniform vector field B = ÅB on a rectangular contour abod in the 2-y plane. (This is the uniform magnetic field between, for example, two wide permanent magnets, as might be seen in a magnetron tube or a medical MRI machine) 5.2 Compute the circulation of the azimuthal vector field B = 4! in the z-y plane at radius r. (This is the magnetic field of an infinite wire carrying unchanging current I in the z direction. Note the use of the unit tangential vector : This equation is in cylindrical coordinates not so hard, is it? )
