Webster's Revised Unabridged Dictionary
    • n Solenoid (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.

    • n solenoid A helix of copper or other conducting wire wound in the form of a cylinder so as to be nearly equivalent to a number of equal and parallel circular circuits arranged upon a common axis. The ends of the wire are brought to the middle point, and when a current is passed through the circuit the solenoid behaves, as far as external action is concerned, like a long and thin bar magnet, For this reason, such a magnet is called a solenoidal magnet; and Ampère's theory of magnetism is based on the assumption that magnets and solenoidal systems of currents are fundamentally identical.
