A 1.8 m long solenoid is 15 cm in diameterand consists of 2010 turns of wire. The current in the solenoid is increasing at the rate of 1.0 kA/s.
a) Find the current in a wire loop with diameter 10 cmand resistance 5.0 , lyinginside the solenoid in a plane perpendicular to the loop axis.
b) Repeat for a similarly oriented loop with diameter 25 cm, lyingentirely outside the solenoid.
