Question

B. [12 points total] Charge is spread uniformly across an i Each square meter of this sheet carries a charge of 24 uC. The sheet moves in the +r direction with a infinitely-large thin sheet lying in the ry plane. constant speed of 8.0 m/s as shown. a Moving sheet of charge +24 uC/m 8.0 m/s y Amperian loop the Sin le the chase S + te t (a) [2 points] What is the direction of the magnetic field just above the sheet (that is, for Circle one choice: z > 0)? fiulel peint n the-Nof +y +2 +x -x y (b) [8 points] Use Ampère's Law to find the magnetic field at a distance of 2.0 m above the sheet. one above the Consider a rectangular loop with two sides, each of length , parallel to the y axis, moving sheet of charge and the other below. In doing so, you may wish to consider the following questions: In one second, what area of the sheet passes through the loop? As a result, how much charge passes through the loop every second? For each of the four straight segments of the rectangular loop, what is an expression, in terms of numerical values and symbols, for f B di?

(In other words, how does the magnetic field depe on distance from the moving sheet?) -S Srs Can L
