A solenoid is a type of electromagnet when the purpose is to generate a controlled magnetic field. If the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

A solenoid has consist of the two pole winding, the plunger is rotating the magnetic flux cut the AC will be generated.

The solenoid is end pole flux area making north pole to south pole and than emf is a generating fellow of current.
