So"len*oid (?), n.[Gr. &?;&?;&?; channel
+ -oid.] (Elec.) 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.
