EE 101 Homework 4: DUE NOVEMBER 14TH Monday noon (12pm); (THERE IS A COLLECTION HW CABINET MARKED “EE101” IN ROOM 67-112 ON THE 6TH FLOOR OF ENGR IV.) 1. A long wire carrying a current I folds back with a semicircular bend of radius ‘ b ’ as in figure below. Determine the magnetic flux density at the center point P of the bend. 2. Assume an infinitely thin plate of current which is placed on X-Y plane (normal to Z plane) carrying the surface current with surface current density of ° ± ² . Find magnetic field (H) and magnetic flux density (B) at all points in the space. 3. The electric field of an electromagnetic wave ³ ´⃗ = ² ³ 0 cos[ 10 8 µ ¶· − ¸ ¹ º + » ] is the sum of ³ 1 ´´⃗ = ² 0.03 sin[ 10 8 µ ¶· − ¸ ¹ º ] and
