Solve the all parts of following question:
Question: The inductance of a solenoid with 460 turns and a length of 23cm is 7.5mH.
Part A: What is the cross-sectional area of the solenoid?
Part B: What is the induced emf in the solenoid if its current drops from 2.9A to 0 in 60ms?
I need help to find the cross-sectional area of the solenoid and express your answer using two significant figures.
