Compute all parts of given problem:
Problem: Suppose a long solenoid is wound with 1000 turns per meter and the current in the windings is increasing at the rate of 100.0 A/s. The cross-sectional area of the solenoid is 4 cm2.
Part A: What is the rate of change of the flux in the solenoid?
Part B: What is the induced emf?
Part C: How is the direction of the emf related to the direction in which the current is increasing?
I want help to determine the rate of change of the flux in the solenoid.
