Cross-section of solenoid Looking through the solenoid solenold Problem 4 (15 points) A solenoid is 20.0 cm long, has a radius of 0.50 cm and consists of 200 windings. Inside the solenoid is a square wire loop with side length 0.70 cm, as pictured square wireloop

a) Sketch the magnetic _eld of the solenoid when current is in the direction pictured. Draw magnetic field lines inside and outside of the solenoid. b) What is the magnitude of the magnetic field in the center of the solenoid if a current of 0.25 A is passed through the coils? c) Using your answer to part b), what is the magnetic flux through the square loop of wire sitting inside the solenoid?
