In the most common form of lightning, electric charges flow between the ground and a cloud. The flow changes dramatically over short periods of time. Even without directly striking an electrical appliance in your house, a bolt of lightning that strikes nearby can produce a current in the circuits of the appliance. Note that such circuits typically contain coils or loops of wire. Why can the lightning cause the current to appear

Lighting bolts are sources of electric energy that change over time producing field of magnetic energy that also changes over time. So, when this field passes through a coil or loop of wire in an installation. It can create an induced emf that can transform into an induced current.

Explanation:

Lighting bolts are phenomenons made of pure electric energy that by correlation conduce a current. Now, this type of current by being electric can create an electromagnetic field of energy. Which at the same time will change over time because it derives from the electric source of energy originated in the lighting bolt. Thus, when this magnetic field that is always in movement passes through a coil or loop of wire will create an induced
