An electromagnetic device is shown below. The coil in the left side is connected to
a steady AC power source. The left coil generates a changing magnetic flux, which is =
1.5cos(120πt +л/6) T. Calculate the voltage vs generated across the right coil given the
number of turns of the right coil is 5 (You only need to calculate the magnitude).
