Post-Fault Demagnetization of a PMSG Under Field Oriented Control Operation

IEEE Access, 2021
To assess demagnetization, a line-to-line short-circuit fault study is carried out with constant input torque and field-oriented control (FOC) for the speed of a permanent magnet synchronous generator (PMSG).

Pulsed-field magnetization of drilled bulk high-temperature superconductors: flux front propagation in the volume and on the surface [PDF]

, 2009
We present a method for characterizing the propagation of the magnetic flux in an artificially drilled bulk high-temperature superconductor (HTS) during a pulsed-field magnetization.

Characterization of trabecular bone by dipolar demagnetizing field MRI [PDF]

Magnetic Resonance in Medicine, 2001
AbstractA multiple spin‐echo (MSE) sequence has been applied for the first time to study trabecular bone ex vivo. The second echo generated by the demagnetizing field presents discrete drops in signal intensity for certain values of the pitch of the magnetization helix created by the correlation gradient.

Monitoring Redox Pathways and Performance Limitations in Lithium‐Sulfur Batteries Using In Situ 7/6Li and 33S NMR Spectroscopies

Angewandte Chemie, EarlyView.
Lithium‐sulfur (Li‐S) batteries contain various NMR‐active nuclear isotopes, including 7Li, 6Li and 33S, which are sensitive to the different chemical reactions that occur during battery cycling. Herein, we use a combination of lithium and sulfur operando NMR spectroscopy to provide new insights at the molecular level, fundamental understanding being ...

Degradable Magnetic Composites from Recycled NdFeB Magnets for Soft Actuation and Sensing

Advanced Robotics Research, EarlyView.
This work presents a degradable soft magnetic composite made from recycled NdFeB particles embedded in a gelatin‐based organogel. The material is processed into magnetic sensors and soft robotic components, which can later be dissolved in a green solvent to recover NdFeB magnetic particles.
