Working with the solenoid, we next turn off the current source to it and immerse it in a uniform magnetic filed
parallel to the axis of the solenoid, with its value changing with a frequency of f-60 Hz, by B = B. Cosat.
d) What is the heat power generated in this solenoid circuit?
c) Calculate the flux of this B-filed through the solenoid as a function of time and use the Faraday's law to
determine the value of Bo such that the maximum generated current is 0.5 A in the solenoid. (At this time,
the two ends of the solenoid wire is connected to form a closed circuit)
