DCfält
DCfält is a term used to describe a constant field generated by direct current (DC). In physics and engineering it can refer to a constant electric field or a constant magnetic field, in contrast to time-varying fields produced by alternating current (AC).
An electric DC field arises from a static voltage difference and is often treated as time-invariant. In
A magnetic DC field is produced by steady currents or by permanent magnets and is also time-invariant.
Applications of DCfält include powering electronic devices, characterizing material responses to steady fields, and serving as
