Abstract :
This article presents the design of an equipment that generates magnetic fields in extremely low frequencies (ELF), with variable intensity in the magnetic field, frequency and exposure time, to be used in biological tissues. The system consists of a Helmholtz coil and a programmable instrumentation to produce magnetic field intensities from 2 to 85 gauss, in a continuous or pulsed option. The duration of the pulses may vary from 1 to 10 seconds and the frequency can be programmed between 1 and 300 Hz. The testing time can be selected from 5, 10 and 15 minutes. The main use of this system is to explore the effect of the magnetic fields in MDCK-type cell cultures.
