Question

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

Answer 1

Electromagnet:

1. A magnet that consists of a piece of iron or steel surrounded by a coil is known as an electromagnet.
2. The metal becomes magnetic when an electric current is passed through the coil.
3. Electromagnets are different from permanent magnets.
4. Electromagnets are made of coils of wire with electricity passing through them.
5. Moving charges create magnetic fields, so when the coils of wire in an electromagnet have an electric current passing through them, the coils behave like a magnet.

In the case of uninsulated copper wire:

1. The copper wire around an electromagnet is insulated to avoid current flow between the wires.
2. If the wire is uninsulated, the current will take a shortcut and will not flow multiple times around the core.
3. If you don't use insulation, you run the risk of shorting the current on the coil.
4. If the current does not flow as a loop, then the magnetic field will not be created.

Hence no electromagnet will be created in that case.
