Solenoid coil design calculations pdf

A simple electromagnet consisting of a coil of insulated wire wrapped around an iron core. A core of ferromagnetic material like iron serves to solenoid coil design calculations pdf the magnetic field created.

The strength of magnetic field generated is proportional to the amount of current through the winding. This drawing shows a cross section through the center of the coil.

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. The magnetic field disappears when the current is turned off. Electromagnets usually consist of insulated wire wound into a coil.

A current through the wire creates a magnetic field which is concentrated in the hole in the center of the coil. The main advantage of an electromagnet over a permanent magnet is that the magnetic field can be quickly changed by controlling the amount of electric current in the winding.
