Question

What will happen if you use an uninsulated copper wire for making an electromagnet

Answer 1

Answer:

The copper wire around an electromagnet is insulated to avoid current flow between the wires. If the wire is uninsulated the current will take a short cut and will not flow multiple times around the core. If the current does not flow as a loop then the magnetic field will not be created.

Answer 2

Answer:

A simple electromagnet consisting of a coil of wire wrapped around an iron core. A core of ferromagnetic material like iron serves to increase the magnetic field created.[1] The strength of magnetic field generated is proportional to the amount of current through the winding.[1]
