Unformatted text preview: The induced charge density on the top surface of ground plane. d y x P(x, y) l Problem 3 (20 points) Assume that N turns of wire are tightly wound on toroidal frame of a rectangular cross section with dimension as shown in the Fig 3. Assume the permeability of the medium to be µ o . 1. (10 points) find the magnetic field H and magnetic flux density B inside the toroidal. (a<r<b) 2. (10 points) find the selfinductance of the toroidal Problem 4 (25 Point) The rectangular loop of N turn is coplanar with long straight wire carrying the current I. Please find: a). (5) The magnetic flux density B (r) due to straight wire ( need derivation ) b). (10) The magnetic flux though the loop c). (5) The magnetic flux linkage d). (5) The mutual inductance L 12 z I r 1 r 2 l r Problem 5 (5 Points) Prove the conductance G and capacitance of structure shown in the figure satisfy following relationship G / C = σ/ε condu ctor cond uctor ε, σ V I...
