"Inductive coupling (electromagnetic)occurs where the source and receiver are separated by a short distance (typically less than a wavelength)." "Inside and about four feet away from thousands of amps was an IBM PC." This is not the same as the phase wires wrapped around the grounded conductor, a similar situation to the windings of a transformer.
NASA studies have concluded that near strikes have caused data changes in on-board computers on rockets. That would suggest that there is some inductive coupling going on there.
The NOAA national storm laboratory states
"Cloud-to-ground lightning can kill or injure people by direct or indirect means. The lightning current can branch off to a person from a tree, fence, pole, or other tall object. It is not known if all people are killed who are directly struck by the flash itself. In addition, flashes may conduct their current through the ground to a person after the flash strikes a nearby tree, antenna, or other tall object. The current also may travel through power or telephone lines, or plumbing pipes to a person who is in contact with an electric appliance, telephone, or plumbing fixture."

OCS ( Oregon Climate Service Oregon State Univ. ) states
"Lightning can travel over the surface of the ground and through the ground. The ground surface can be lethal for up to 60 feet radius or more from the point of contact. This also includes a ground rod as the point of contact. In water, the lethal radius is about 600 feet from point of contact."
