Within the last few years, the first testing devices have been launched that allow practical demagnetization of transformers on-site. When a transformer is re-energized, an inrush current occurs that ...

This magnetic strip is susceptible to demagnetization, which can occur due to prolonged exposure to magnetic fields (or physical damage). When a magnetic strip becomes demagnetized, the data ...

During ultrafast demagnetization of a magnetically ordered solid, angular momentum has to be transferred between the spins, electrons, and phonons in the system on femto- and picosecond timescales.

Adiabatic demagnetization is an efficient technique for cooling solid samples by several orders of magnitude in a single cooling step. In gases, the required coupling between dipolar moments and ...

In the study, a team led by Konstanz researchers investigated the demagnetization of nickel crystals using ultrafast electron diffraction—a highly precise measuring method in terms of time and ...

In battery-charger applications, you usually wire the auxiliary winding—the one that self-supplies the controller and gives the demagnetization signal—in forward mode. The reason is simple: When the ...

An important consideration in electrical machine design is the demagnetization due to high currents and temperatures. Simulation accuracy is dependent on realistic material models. This paper ...

Get Instant Summarized Text (Gist) Ultrafast spin-polarized current pulses were directly characterized in magnetic layer systems by measuring demagnetization dynamics within hundreds of ...
