Sketch the electric and magnetic field line patterns produced by the four situations shown in Figure P30.13:

(a) a stationary charged rod carrying a linear charge density of \(+\lambda\) 

(b) a charged rod carrying a linear charge density of \(+\lambda\) that moves at constant velocity along the length of the rod,

(c) a stationary charged rod carrying a linear charge density of \(+\lambda\) that is infinitesimally close to a parallel stationary charged rod carrying a linear charge density of \(-\lambda,(d)\) a charged rod carrying a linear charge density of \(+\lambda\) that moves at constant velocity along the length of the rod and is infinitesimally close to a parallel charged rod carrying a linear charge density of \(-\lambda\) and moving in the opposite direction.
