Why a copper wire is insulated in a solenoid?

Expert Answer:

Dear student,
 
To resist the corrosion, the copper wires are coated with enamel.The enamel insulation of magnet wire is formed of a chemical called polyesterimide. The wire can withstand temperatures of 356 degrees Fahrenheit for at least 20,000 hours. This makes enameled copper wire capable of carrying more current than wires of the same size insulated with anything else.
 
Hope this helps.
