     Background & Aim: In human environment, magnetic fields are created by electrical generators, power lines, and electrical instruments. These fields could affect learning and memory. This study was planned to evaluate whether short time exposure to magnetic fields has any significant effect on spatial memory. Material & Method: In this experimental study, we used 10 male Albino Wistar mice ...
