Electromagnetic induction detection techniques for craniocerebral injury: A review

“…According to the electromagnetic induction principle, the presence of cerebral bleeding leads to the production of eddy current, causing a decrease in the coil's inductance and an increase in resistance. The eddy currents also produce magnetic flux, which reduces the flux density of the total magnetic field [26]. By comparing the variations in magnetic flux density between normal tissue and hemorrhagic tissue, pictures of cerebral hemorrhage are created.…”

Modeling Frequency-Dependent Core Loss of Ferrite Materials Using Permeance–Capacitance Analogy for System-Level Circuit Simulations

“…Please note that there is no magnetic resistor placed at the left hand side of the hysteresis permeance, which was present in the structure proposed by [23] mainly accounting for eddy current effect. This complies to the fact that we neglect the eddy current effect of ferrite materials, which has negligible contribution to the core loss, compared to the relaxation effect and frequency independent hysteresis.…”
