Physics

Why do the voltage and current in the pickup coil cycle betweennegative and positive? Explain in detail using Faradayâ€™s Law.Remember, Lenzâ€™s Law is part of Faradayâ€™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 Faradayâ€™s lawequation)

The voltage and current in the pickup coil cycle between negative and positive because of the reason that How the magnetic flux through the loop changes as the magnet rotates as the magnet rotates the magnetic flux interacting with the loop changes that is when magnet rotates its one part is near to the loop so flux through the loop increases and when this part goes away See Answer
