A coil has 400 turns and self-inductance 4.80mH . The current in the coil varies with time according to i=(630mA)cos[pit/(0.0250s)]. Part A Max Emf induced in the coil =0.410V Part B Max flu through each turn of the coil= 8.16*10-6 Wb Part C At = 0.0180 , what is the magnitude of the induced emf?(CAN'T SOLVE THIS PART)
