A temporary magnet made of wire coiled around an iron core
Real World Example
Imagine you're trying to keep a stack of papers organized with a paper clip. Just as the paper clip temporarily holds the papers together when clipped, an electromagnet temporarily becomes a magnet when electricity flows through the coiled wire around the iron core. In this analogy, the paper clip is like the iron core, and the act of clipping is akin to the electric current; both create a temporary binding effect, whether it's holding papers or turning the iron into a magnet.
