A single coil with a radius of 0.02 m is placed inside a 3m longsolenoid that has 600
turns. The radius of the solenoid is 0.15 m. The plane of the coilis perpendicular to the axis of the solenoid. The solenoid isconnected to a battery, an ammeter and a switch. The ammeterreaches 5A in 0.2 seconds and remains constant. The change in themagnetic flux across the small loop is 1.58 x 10^-6 T.m^2. Theaverage induced emf (voltage) in the small loop is 7.9 x 10^-6 V.Another solenoid has an inductance of 8.000 henries and aresistance of 2.772O. It is connected to a battery and a switch.How long does it take for the current to reach half of its maximumvalue after the switch is closed?

I cannot figure out which equation to used in order to solve this.I know the current must be determined, but I am not sure how to dothat with knowing only the inductance and the resistance. I knowI'm probably over-thinking this, but everything I've tried does notgive the correct answer. Can someone please help me figure thisout?
