Two identical exposure systems were built, one for exposure and one for the control animals. The exposure system and the control system were separated by 3.5 m to reduce any stray fields. Rats were randomly split in two cages (48 x 26 x 15 cm; length x breadth x height) made of polypropylene. Control rats were placed in two cages located in the center of the control system (without magnetic field).
The magnetic field was arranged and produced by sets of rectangular coils similar to that reported by Juutilainen et al.  publication id 3704. Details of the experimental set up have been reported by Al-Akhras et al.  publication id 6741 and Elbetieha et al.  publication id 8513.
