The detail that a force exists on a wire carrying a current in a magnetic field has an interesting application when we consider a current carrying loop. When the area vector is at right angles to the ...

• The inductance in a stepper-motor phase winding limits how fast current rises when power is applied. • Series-resistor current limiting needs higher voltages for faster step rates, but higher ...

ITHACA, N.Y. - Tomorrow's nonvolatile memory devices – computer memory that can retain stored information even when not powered – will profoundly change electronics, and Cornell University researchers ...
