(a) Two long straight parallel wires each carry a +3 A current in the same direction out of the page, as shown in Figure 1. hem S 2 cm 8 cm 8 cm 1 cm elslq +3 A Q +3 A R Helle hem 17 cm Figure 1. State and justify your answer to each of (i), (i) and (ii) below (detailed calculations are not required). At which of the points P, Q, R and S is the magnetic field strongest? At which of the points P, Q, R and S is the magnetic field weakest? The direction of the magnetic field at R. (i) (iii) Ampere's circuital law states that the closed path integral of the magnetic (b) field B is equal to the current enclosed by the path multiplied by the magnetic permeability, µo. That is, mathematically, gB•ds = µoienclosed- Assuming cylindrical symmetry, derive an expression for the magnitude of the magnetic field B at a distance r from the axis of a long straight wire carrying a current i, where r lies outside of the wire. Determine the magnitude and direction of the magnetic field produced by (c) the two currents at the points P and S in Figure 1. (Ho = 4 × 10-7 H m-1) %3D 4.
