Learning Goal: To understand the terms in Faraday's law and to be able to identify the magnitude and direction of induced emf. Faraday's law states that induced emf is directly proportional to the time rate of change of magnetic flux. Mathematically, it can be written as E=???B?t, where E is the emf induced in a closed loop, and ??B?t is the rate of change of the magnetic flux through a surface bounded by the loop. For uniform magnetic fields the...

Part E - Use phasors to subtract one sinusoid from another sinusoid Suppose you want to find the difference of two sinusoidal currents, given as follows: ¿1(t) = 1; cos(wt+$1) and iz(t) = 12 cos(wt+$2). If you stay in the time domain, you will have to use trigonometric identities to perform the subtraction. But if you transform to the frequency domain, you can simply subtract the phasors I1 and 12 as complex numbers using y calculator. Make sure that all...
