We do know from our Electricity 101 class, that electrical induction is a
proven phenomena and if a large enough voltage is applied near a conductor,
a current WILL be induced.

.....25 Years ago, I was using the K6LY Navy School Club Station, which was
in a metal building, inside the base of a 120 ft Metal tower, 20 ft on a
side, and had a TH-6DXX tribander on top. We experienced one of the rare
thunderstorms of the area, so I disconnected the HF antenna coax, from the
HF station, and placed it about 2" from the steel enclosed cable tray that
was embedded in the concrete floor.
I sat back and operated handheld VHF, while listening to the thunder and
lightning outside. Most of the observable lightning flashes, you could see
indirectly, through the windows, caused a powerful POP, and brilliant
Flashover arc between the coax (shield, probably) and the grounded steel
cable box, and the smell of ozone. It was a memorable wait out of a rare
thunderstorm in Monterey. No direct hits, but it would have probably been
wiser to toss the HF antenna Coax out the widow, to keep potential BIG
sparks outside.
All the Best, 73,
