Show me the steps to solve

$($b$)$ Find the Thevenin equivalent of the terminal $\backslash ($ a$,$ b $\backslash )$ of the circuit in Figure $1\mathrm{.}2.$ If a load as shown in Figure $1\mathrm{.}3$ is connected to the terminals $\backslash ($ a$,$ b $\backslash ),$ determine the steadystate current of the inductor.
