Dual coil EMF exposure system

Dual coil EMF exposure system

These generators are Helmholtz coil systems that consist of two square frames measuring 1.5 m on each side with an external 750-W power supply capable of operating in both AC and DC mode. When paired, this system can deliver a uniform field (<5% variation) over approximately 60cm length x 150cm width x 100cm height, with field strengths up to 3.2 mT.
