Safety of the magnetic field generated by a neuronal magnetic stimulator: evaluation of possible mutagenic effects.

Objective: The possible mutagenicity of a magnetic stimulus was checked using the Ames test with Salmonella typhimurium TA98 and TA100 as tester strains.

Methods: Samples of these bacteria were exposed to a pulsed magnetic field, on the order of 1 T. The magnetic pulses were generated by a neuronal magnetic stimulator with a flat coil.
