electromagnet
A magnet whose magnetic force is produced by electric current; common in science, technology, and everyday explanations of devices.
When an electric current flows, an electromagnet attracts iron.
The crane lifted scrap iron with a powerful electromagnet.
We passed current through the coil to turn it into an electromagnet.
The electromagnet attracted the scrap iron.
We increased the number of coil windings to strengthen the electromagnet's force.
