Lightning bolt strikes a lightning rod

Reference no: EM13654905

When a lightning bolt strikes a lightning rod, its current istypically conducted to the ground by a ground rod. When the currentin the rod exceeds 20.0 kA, it can no longer be confined bythe rod and will arc laterally through the air to the ground. What is the strength of the magnetic field 7.50 m froma ground rod that is conducting current at the limit of its capabilities? Treat the ground rod as a long, straight wire.
