Consider a solenoid oriented on a horizontal surface from north to south. We know that self-induced emf in this solenoid is not zero and directed from south end of solenoid to north end. We can conclude from this fact that current though this solenoid is

a. passing from south end of solenoid to north end and is decreasing in magnitude

b. passing from north end of solenoid to south and and is increasing in magnitude

c. passing from south end of solenoid to north end and is increasing in magnitude

d. there is not enough information given to answer this question

e. passing from north end of solenoid to south end and is decreasing in magnitude
