In silico evaluation of adverse eddy current effects in preclinical tests of magnetic hyperthermia

open access: yesComputer Methods and Programs in Biomedicine, 2022
Magnetic hyperthermia is an oncological therapy that employs magnetic nanoparticles activated by alternating current (AC) magnetic fields with frequencies between 50 kHz and 1 MHz, to release heat in a diseased tissue and produce a local temperature increase of about 5 °C. To assess the treatment efficacy, in vivo tests on murine models (mice and rats)

Eddy Current Transducer with Rotating Permanent Magnets to Test Planar Conducting Plates [PDF]

open access: yesSensors, 2019
In this paper, we present an eddy current transducer with rotating permanent magnets for the inspection of planar conducting plates. The transducer consists of a rotating head with permanent magnets, which is used to generate variable magnetic fields and thus induce eddy currents in the tested material.
