Main measurement and automation nodes of magnetic nanoparticles heater: student project

At carrying out the experiments to determine the losses for heating of magnetic nanoparticles (MNP) and composites on their basis, which are commonly used in the cancer treatment, it is necessary to reduce the number of manually regulated processes, e.g.: frequency change and resonance adjustment, alternating magnetic field strength amplitude change, as well as the measurements. In present article structural diagram of device for such purposes with improved automation level is presented and circuit engineering solutions for main measurement and automation nodes are proposed. There is an attempt to perform a purely electronic control of current ﬂowing through the heating solenoid coil to adjust the magnetic field strength applied to the MNP sample without using any additional power electronics components.
