  6. Ring ground - Wikipedia

    en.wikipedia.org/wiki/Ring_ground

    When lightning strikes a metal tower or strikes near a building containing electrical equipment, a large, rapidly changing magnetic field is generated. This magnetic field induces current onto power lines, often disrupting electrical service, and also induces current into other electrical conductors such as electrical equipment and even ...
