2. As the wire that makes up the coil passes a variable current, a varying magnetic field exists around the coil.
3. The coils can contain a variable current, but typically utilize high voltages, and therefore require significant insulation in order to prevent short-circuiting the lens components.
4. The agency, one official said, has also never tried to clean a river like the Hudson, which is legendary for its swift and variable currents.
5. For instance, the " across " variable voltage is the analogy of velocity, and the " through " variable current is the analogy of force.
6. It's difficult to find variable current in a sentence. 用variable current造句挺难的
7. Large electromagnets are usually powered by variable current electronic power supplies, controlled by a microprocessor, which prevent voltage spikes by accomplishing current changes slowly, in gentle ramps.
8. There are no experimental chambers to regulate water flow, and thus allows for natural near-bottom flow conditions, but it generates highly variable pH under variable current speed or direction.

10. The Murray Mouth is the point at which the Murray River empties into the sea, and the interaction between its shallow, shifting and variable currents and the open sea can be complex and unpredictable.
11. This topology is approximately preserved even when the magnetic field itself is strongly distorted by the presence of variable currents or motion of magnetic sources, because effects that might otherwise change the magnetic topology instead induce eddy currents in the plasma; the eddy currents have the effect of canceling out the topological change.
