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.
a. How the magnetic flux through the loop changes as the magnetrotates (is the flux maximal when the magnet is horizontal orvertical on the screen? Why?)
b. How this changing magnetic flux works to create an emf(potential difference) in the coil which alternates over time (usethe Faradayâ€™s law equation)

The voltage and current in the pickup coil cycle between negative and positive because of the reason that here the nature of the current induced in the pickup coil is alternating In nature in which the movement of electron determines the type of cycle which causes the cycle of positive and negative And the the following points we have to consider as aHow the magnetic flux through the loop changes as the magnet rotates as See Answer
