A transmitter loop is carried by a first aircraft. A receiver sensor is carried by a second aircraft. The first aircraft and the second aircraft fly away from each other. The transmitter loop transmits a primary magnetic field. The transmitted primary magnetic field induces a current in the earth. The induced current generates a secondary magnetic field in the air. The receiver sensor receives the generated secondary magnetic field, and detects strength of the received secondary magnetic field.
