9.3. A system of two conductors has a cross section given bythe intersection of two circles of radius b with centersseparated by 2a as shown in figure below. The conductingportion is shown hatched, the non-hatched lens-shaped regionbeing a vacuum. The conductor on the left carries a uniformcurrent density, J1, coming out of the page, and theconductor on the right carries a uniform current density, −J 12,going into the page. Assume that the magnetic permeability ofthe conductor is the same as that of the vacuum. Find themagnetic field at all points in the vacuum enclosed betweenthe two conductors.2a

5. Consider two (1 and 2) wires both having constant circular cross sectional areas: wire 1 has diameter = d, ; wire 2 has diameter = d. Potential differences are applied across each wire so that they both carry current. The current in wire 1 is I, and in wire 2 it is I, ; the the magnitude of the current density in wire 1 is J, and in wire 2 it is J,. If I,= I, and J, = (2) J, then wire diameters must be such that d, = (?) d. a. 2/2 b. V212 c. 2 d. V2 e. V214
