Electromagnetism: Principles and Applications

 A simple electromagnet consists of an
insulated wire coil wrapped around an iron
core.
 A core of ferromagnetic material, like iron,
serves to increase the magnetic field
created.
 The strength of the generated magnetic
field is proportional to the amount of current
that passes through the windings.
