2. a) A dense bundle of insulated cables is shown in Figure Q2a. Each cable carries a DC current as shown where I is the current. The direction of the currents are indicated with currents flowing into the page taken as positive. i) For I = 2 A obtain the applied field strength at a distance of 1.5 cm from the 4 bundle. ii) 6 The bundle is encased in a medium of unknown permeability. The resultant field at a radius of 1 cm is measured to be 130 ut when I = 1.5 A. Determine the material's relative permeability. 0.21 1.5 1 0.75 1 (+ 0.71 0.41 1.21 Figure Q2a
