Design and use of a gradiometer connected rubidium magnetometer

Abstract
Two rubidium magnetometers are connected by a telephone link and are used to study magnetic field differences between Exeter and Sidmouth (a separation of about 18 miles) in Devon, England. The system has a noise level of less than 50 mγ and is notable for its simplicity. Some advantages of the system are demonstrated by examples of the results obtained, which illustrate coastal and tidal effects in the geomagnetic variations.
