The paper describes the design of a magnetic stimulator for studying the effect of ferromagnetic nanoparticles on biological objects in a magnetic field. In a magnetic stimulator, an electromagnet acts as a source of exposure, which creates an alternating magnetic field. To register the magnitude of the magnetic field created a special device based on Arduino. The presented magnetic stimulator can be used in the study of biological objects in vitro and in vivo. The stimulant is made of inexpensive, readily available components.
