EE 101: H omework6 : DUE NOVEMBER 21st Friday 2pm (THERE WILL BE A COLLECTIONB OX IN MARIKO WALTON'SC UBICLEO N THE 6THF LOORO F ENGRI V.) 1. The circular disk shown below lies in the x–y plane and rotates with uniform angular velocity w about the z-axis. The disk is of radius a and is present in a uniform magnetic flux density . Obtain an expression for the emf induced at the rim relative to the center of the disk. 2. In a certain medium, the direction of current density J points in the radial direction in cylindrical coordinates and its magnitude is independent of both and z . Determine J , given that the charge density in the medium is v _  0* r cos t & ( (C/m 3 ) 3. The electric field of an electromagnetic wave propagating in air is given by (V/m).
