Definitions for "Solenoid"
An electrodynamic spiral having the conjuctive wire turned back along its axis, so as to neutralize that component of the effect of the current which is due to the length of the spiral, and reduce the whole effect to that of a series of equal and parallel circular currents. When traversed by a current the solenoid exhibits polarity and attraction or repulsion, like a magnet.
A coil of wire in the form of a cylinder that, when carrying a current, resembles a bar magnet.
a helical winding of wire that, when carry a current, produces a uniform magnetic field near its center (see figure 19.30)
A tube formed in space by the intersection of unit-interval isotimic surfaces of two scalar quantities. The number of solenoids enclosed by a space curve is therefore equal to the flux of the vector product of the two gradients through a surface bounded by the curve, or where is the vector element of area of a surface bounded by the given curve. Solenoids formed by the intersection of surfaces of equal pressure and density are frequently referred to in meteorology. A barotropic atmosphere implies the absence of solenoids of this type, since surfaces of equal pressure and density coincide. See also baroclinity, vorticity equation, circulation theorem.
Solenoids are commonly used in "dumb" cash drawers and incorporate a cable connected trigger which releases the drawer. Cash drawers with solenoids are interfaced to receipt printers that "drive" them. Solenoids have different voltages and are integrated into the cash drawer dependent on the printer they are interfaced to.
