Development of Young Mice

  • Jeno M. Barnothy


Experiments on the influence of static magnetic fields upon the development of young mice were first made in 1948 at the University of Budapest. Half of a litter of six 5-week-old mice were kept in the vertical field of an electromagnet, the other half of the litter in identical dummy magnet cages (pole pieces simulated; same temperature, light, and ventilation), for a period of 4 weeks. The aluminum cages were 38 mm in height and 75 mm in diameter with hard-rubber bottoms, surrounded by an open tray where food and water were provided. The design of the electromagnet, heat insulation, and cooling fins used prevented any observable increase of the temperature of the cage walls. A forced air blow prevented the mice from staying for long periods outside their cage. They never attempted to escape, thus proving the adequacv of their housing conditions.
