Abstract: The Faraday rotation measurements of multiply-imaged gravitational lenssystems can be effectively used to probe the existence of large-scale orderedmagnetic fields in lensing galaxies and galaxy clusters. The available sampleof lens systems appears to suggest the presence of a coherent large-scalemagnetic field in giant elliptical galaxies somewhat similar to the spiralgalaxies.
