Need HELP- with magnetic field

Image for A magnetic field is described by B vector = B0ksin omega t, where B0 = 1.8T and omega = 12s^-1. A conducting l

Answer 1

Answer #1

Induced EMF e = d(BA) / dt = A dB/dt

e = (200 x 10^-4) x d(1.8sin12t) / dt

= 0.02 * 1.8 *12 cos12t

e(t) = 0.432 cos12t

I(t) = e(t) / R = 0.0332 cos12t

Part A) I(0) = 0.0332 A

Part B. I(0.15) = 0.0332 x cos(0.15*12) = 7.543 x 10^-3 A
