A 85-turn circular coil has diameter 4.3cm and resistance 2.9O. This coil is placed inside a solenoid, with coil and solenoid axes aligned. The solenoid has 5000 turns of wire and is 21cm long.
Part A: If the solenoid current increases steadily from 0 to 11A in 2.1 seconds, find the induced emf in the coil.
Part B: If the solenoid current increases steadily from 0 to 11A in 2.1 seconds, find the induced current in the coil.
