Why do the voltage and current in the pickup coil cycle betweennegative and positive? Explain in detail using Faraday’s Law.Remember, Lenz’s Law is part of Faraday’s Law! Although it will notbe covered explicitly in this class, this is known as alternatingcurrent. Points to discuss: How the magnetic flux through the loopchanges as the magnet rotates. Is the flux maximal when the magnetis horizontal or vertical on the screen? Why?) How this changingmagnetic flux works to create an emf (potential difference) in thecoil which alternates over time (use the Faraday’s lawequation)
