The alternating magnetic field system and the filler wire swing system both generate magnetic fields that utilize the same alternating power source. This allows the filler wire and the arc to oscillate in unison. Such swing of the filler wire ensures a stable transition between the liquid melt and the sidewall, effectively reducing the contact ...

MNPs in an alternating magnetic field produce heat that can be used for therapeutic applications or activation of components on the MNP delivery platform. Heating is achieved by the change in magnitude of an applied external magnetic field. Brownian relaxation causes friction due to physical orientation of the particles, and changes in internal ...
