A rectangular coil with 6000 turns that has a resistance of 1.5Ω is coplanar with a long wire which carries a current which depends on time according to I0*e(−t / tau), where I0=5 A and tau=4.4 s. The rectangular loop has a width of W=2 cm and length L=7 cm. The near side of the loop is a distance D=7.7 cm from the wire.
A) What is the magnetic flux in ONE turn of the coil at t=3.6 s? for my answer I got 1.62E-9 Wb which was wrong.
B) What is the emf in the entire coil at t=3.6 s? For the purposes of entering a sign, let the positive direction for the emf in the loop be in the clockwise direction. for my anwer I got 9.7E-9 V/m which was wrong.
C) What is the power dissipated in the entire coil at t=3.6 s? for my anser I got 21.4E-9 W which was wrong
D) What is the total energy dissipated in the entire coil from t=0 to t=3.6 s? for my answer I got 6.7E-9 J which was wrong.

- A 3.0-cm-diameter, 18-turn coil of wire, located at z = 0 in the xy-plane, carries a current of 2.5 A. A 2.0-mm-diameter conducting loop with 2.0 x 10-4 resistance is also in the xy-plane at the center of the coil. At t = 0 s, the loop begins to move along the z-axis with a constant speed of 75 m/s. Part A What is the induced current in the conducting loop at t = 200 us? The diameter of the conducting loop is much smaller than that of the coil, so you can assume that the magnetic field through the loop is everywhere the on-axis field of the coil.

A magnetic field B = 0.25 T points out of the page. The rails are seperated by 35.0 cm.What emf is generated?

At t = 0, there is a small sphere carry- ing charge +9o at x = a and a small sphere carrying charge -9o at x = -a. As the spheres discharge and a current is established in the wire, show that, for t>0, the generalized form of Ampère's law (Eq. 30.13) and the Biot-Savart law (Eq. 28.12) give the same result for the magnitude of the mag- netic field a distance b up the y axis. (Hint: Obtain the elec- tric flux through a circular disk in the yz plane, centered at the origin. Because the electric field is not constant over the surface of the disk, you must divide the disk into a nested set of rings of various radii and integrate. A representative ring should have radius r and radial extent dr.) •..
