In this work, low-frequency wide-pulse electric and magnetic field simulators, which enable the adjusting of waveform parameters and output intensity, are presented. The uniformity of electromagnetic fields produced by the simulators is tested. The electric field generator is shown to create low-frequency wide-pulse irradiation electric fields with the highest peak amplitude of 100 kV/m, the fastest rise time of 10 ns (can be adjusted to microseconds), the pulsewidth greater than 1 ms, and the asymmetry degree lower than 10% in a 1.6 ^{3} m ^{3} cubic space. The magnetic field generator is shown to create low-frequency wide-pulse irradiation magnetic fields with the highest peak amplitude of more than 10 mT, the rise time of 10-300 \upmu s, the pulse duration greater than 1.5 ms, and the asymmetry degree lower than 10% in a \pi \times 2 ^{2} m ^{2} (square of radius) \times 5 m (length) spatial domain.
