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
