Question

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

Answer 1

1. An electromagnet's copper wire is insulated to prevent current flow between the wires.
2. If the wire is not insulated, the current will take a shortcut and not run around the core several times.
3. The magnetic field will not be formed if the current does not flow in a loop.
4. When you increase the number of loops of wire around the iron core, the strength of an electromagnet is increased.
5. It also increases by increasing the current or voltage.
