Radiation and a copper wire

A slab $($pulse$)$ of electromagnetic radiation that is $\backslash ($ h$=15\backslash$mathrm$\{$~cm$\}\backslash )$ thick is propagating downward $($in the $\backslash (-$y $\backslash )$ direction$)$ toward a short horizontal copper wire located at the origin and oriented parallel to the $\backslash ($ z $\backslash )$ axis, as shown in the figure.

$($a$)$ The direction of the electric field inside the slab is out of the page $($in the $\backslash (+$z $\backslash )$ direction$).$ What is the direction of the magnetic field inside the slab?

$($b$)$ You stand on the $\backslash ($ x $\backslash )$ axis at location m $\backslash ),$ at right angles to the direction of propagation of the pulse. Your friend stands on the $\backslash ($ z $\backslash )$ axis at location mathrm$\{$m$\}\backslash ).$ The pulse passes the copper wire at time $\backslash ($ t$\_\{1\}=0\backslash ),$ and at a later time $\backslash ($ t$\_\{2\}\backslash )$ you observe new non$-$zero electric and magnetic fields at your location. What is $\backslash ($ t$\_\{2\}\backslash )?($give a numerical answer.$)$
