Two long straight parallel wir long straight parallel wires each carry a 3A current in the same direc- tion out of the page as shown in plan view in Figure 2. 3 cm 8cm 8cm 2 cm +3A +3AE O 17 cm 17 cm Figure 2. (a) Giving your reasons, state: (1) (ii) (iii) at which of the points C, D, E and F is the magnetic field strongest at which of the points C, D, E and F is the magnetic field weakest; which of the following most closely describes the direction of the magnetic field at F: up the page, down the page, to the left, or to the right? (b) Ampere's Circuital Law states that path integral of the magnetic field vector B is equal to the current enclosed by the path multiplied by the magnetic constant Ho. That is mathematically B. ds = Holenclosed Using Ampere's Circuital Law determine an expression for the magnitude of the magnetic field at a distance R from the axis of a long straight wire of radius r carrying a current i of uniform current density where R lies: (0) (ii) outside of the wire; inside the wire. (c) Determine the magnitude and direction of the magnetic field produced at points F and C. The magnetic constant He = 414 x 10-7 TMA-1.
