What is Faraday's Law? o It defines the induced voltage across a coil when the magnetic field going through it changes. o It gives the direction of the induced current going through a coil when the magnetic field going through it changes. O The potential difference across a resistor is proportional to both the resistance and the current going through it O The sum of all the current going into a junction has to equal the sum of all the...

In Lab 11 you simulated how a magnetic field can be produced by a conducting coil when powered by a DC and an AC generators. You explored the differences between the resulting magnetic fields. Consider an experimental set-up identical to what you used in the lab: a large coil connected to an AC power supply. Assume that the maximum voltage supplied by the generator stays the same but the frequency of the supplied voltage changes. As frequency changes, you measure...

An external magnetic field is parallel to the central axis of a 65.0-turn coil of radius 7.50 cm. During an interval of 156 ms, the field changes from 0.180 T in one direction to 0.340 T in the opposite direction. The resistance of the coil is 70.0 Ω. What is the average induced current in the coil during this interval?
