A solenoid is a type of electromagnet whose 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 Use this Air Core Solenoid to provide an external magnetic field where required and to change the rate of magnetic flux passing through a coil. It consists of a plastic spool with windings of insulated copper. It is useful for classroom experiments and demonstrations on magnetic fields. It is used as instrument apparatus for students,schools and laboratory.connect a power supply that does not put out more than 5 amps to the solenoid, with the positive lead at one terminal and the negative lead at the other terminal.
