please answer from d to j sub-part

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 current 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 the distance "x" (from the LONG conductor to the loop. ) USE “+" for CCW circulation and "-" for CW circulation. a function of b) Write the magnetic field in "i-j-k" format at point "x" to the right of the current carrying wire in the "i-z" plane R. a 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.
