PLZ PLZ SOMEONE DO THIS FOR ME ILL GIVE BRAINLIEST Layna and Aaron have made an electromagnet by coiling a copper wire around an iron nail, then connecting the wire to a battery, as seen in Figure 1. This causes electricity to flow through the coil, magnetizing the nail and creating a magnetic field.

Electromagnet diagram. A coil of wire is wrapped around an iron nail and connected to a battery.
