Problem 1: A coil is 15 turns and radius 20 cm surrounds a long solenoid of radius 5 cm and 3000 turns/ meter. The current in the solenoid changes as I = 3 sin ( t) (where I has a unit of Ampere and t has a unit of second) a) Find the magnetic flux through the solenoid cross-section when time equals to 0.5 sec Solenoid N=15 r=20x10-2 r = 5x15² N = 3000 3 sint t SB. dĀ = 0 I= PA = QA = B.A = BA こ t=0.5 B=MONI PON (3 sinat) ??!
