Please Answer D, E, F. Thank you.

. The following picture shows a LONG conductor carrying current I. Nearby there is a
conducting rectangular loop with sides a = 8 cm and b = 4 cm. The loop also carries a
resistance R = 10 ohms. The curent is constant and has a value of I = 6.0 Amperes. The
loop is moving away to the right with a constant velocity, V = 2 m/s. Answer the following
questions at the instant of time t" when the left edge of the loop is at position "x" as shown
below
Use the coordinate system , x to the right, y into the board, z upward
a) Write an expression for the magnetic field as a function of
the distance "x" (from the LONG conductor to the loop. )
USE “+" for CCW circulation and "-"“ for CW circulation.
b) Write the magnetic field in "i-j-k" format at point "x" to the
right of the current carrying wire in the "iz" plane
c) Write the infinitesimal area vector for the loop in "i-j-k"
format
d) Write the explicit integral for the magnetic flux through the
area of the loop using the answer for B and dA above.
Include limits on the area integral In general
e) Integrate the flux integral above to obtain
+ (x) = 40°1-a [1n(x+b) – In(x)]
) Express the position "x* as a function of "r
